- Description
- This combined synopsis/solicitation is being posted to both the Federal Business Opportunities (FBO) page located at http://www.eps.gov and the Navy Electronic Commerce On Line (NECO) site located at http://www.neco.navy.mil. While it is understood that FBO is the single point of entry for posting of combined synopsis/solicitation and solicitations to the internet, NECO is the alternative in case FBO is unavailable. Please feel free to use either site to access information posted by the Naval Sea Systems Command. The pulsed power variable laser system will be purchased on a sole source basis from Spectra-Physics Lasers, Inc. to support several technical areas of interest to NSWCDD and the Navy. The laser system will be able to radiate at high energy levels at varying wavelengths in order to study wavelength dependent phenomenon that is of interest to the Navy DEW program. Spectra-Physics pulsed power laser system is the only system, which fully meets the Governments requirements. The Governments requirements are as follows: a. Tunability. To fully utilize this capability, the laser system must be tunable from the visible (VIS) portion of the spectrum (440nm - 700nm) through the Near Infra-Red (NIR) portion (1000nm - 2600nm) and into the Mid Wave Infra-Red (MWIR) portion (2900nm - 3200nm). b. Energy. The laser system must provide more than 1000 mJ/pulse at 1064nm and at least 10 mJ/pulse of energy in the extended NIR region. c. Turn-key, OTS product. The major components of t! he laser system must be a standard Off The Shelf (OTS)/catalog products of the company, not a research and development item built to meet the specifications of this purchase. The major components include the solid-state pump laser, the solid-state optical parametric oscillator (OPO), and any additional components (or extensions) required for tunability to multiple wavelength selections through 3200nm. In order for the laser system to meet the specified requirements, the major component elements will need to be used in concert. A practical system necessitates all elements be engineered to work well together. Because these elements are intimately coupled, optimization forces iterative procedures between elements. Therefore it is required that the laser system be provided from and backed by a single manufacturer that is well versed and is responsible for support of all elements operating as a single unit. This manufacturer must provide the laser system as a turn-key product! , i.e. a complete and ready to operate laser system upon delivery. d. Laser System. The laser system must have a solid-state pump laser with a solid-state OPO laser. e. Beam quality. It is important for this application that the laser system operates with a balance between efficiency and mode quality. The laser system must use a high quality reflective pump chamber with a gold surface in order to provide the high reflectivity and uniform cross section illumination to ensuring uniform output beam profile (no hot spots). If the pump chamber is ceramic, for example, the mode quality is sacrificed for efficiency because the lamps are coupled closely to the crystal rod, which leads to non-uniform illumination and thus results in lower quality modes and poor beam propagation. In addition the gold-coated chamber provides a long lifetime in comparison to ceramic or powder-based chambers, which will degrade over time because of the UV generated by the flash lamp. In addition! , the laser must utilize a dual rod birefringence compensated oscillator for maximized beam quality and energy, whereby the birefringence induced in the first rod is compensated by the second rod and vice versa. f. Linewidth. The pump laser must have Injection Seeding for 0.003/cm linewidth at 1064 nm. The OPO linewidth must be less than 0.20/cm across the entire tuning range. g. Alignment mode. The laser must incorporate a standard long pulse mode, in addition to the standard nanosecond pulse output. The long pulse must measure approximately 200 microsec so that a pulse with reduced peak power levels can be used for safer alignment of down stream optics. For safety, the laser beam shall be operated in this alignment mode, which turns the Q-switch off and allows the laser to free run at a pulse duration of 200 microsec. This low energy pulse is 1/20,000 of the Q-Switched peak power of the standard 532 nm green pulse and without changing the beam diameter and divergen! ce. So alignment of the laser to the experimental apparatus can be performed at a reduced risk of working with a high peak power beam. In the case of IR only operation, this feature should reduce the peak power by a factor of 15,000. h. High quality Optics. There must be optics within the laser system that have optical coatings with high damage thresholds in order to sustain high peak power. This ensures longer lifetimes of the optics and longer term performance and lowers future maintenance and operating costs. i. Laser Protection and Personnel Safety Measures. The laser must use oil/dust-free stainless steel beam tubes between all optical elements to enclose the entire beam path to add a protective physical barrier against environmental contamination. The beam tubes must be sealed such that they can be purged for optical surface protection and reduced long component lifetime. The beam tubes also must offer an added safety barrier that protects the user when the l! aser head cover is off. Eyewear protective goggles must be available to the correct MPE (Maximum Permissible Exposure) levels as stated in the ANSI eye safety standards for this class of laser system and levels of operation. j. Dual pump chamber oscillator design with birefringence compensation. The compensated oscillator reduces depolarization and improves overall beam quality, especially at higher repetition rates (high average power). k. Beam Pointing Stability. The laser system must maintain beam pointing stability of less than 25 micro rad over an 8-hour period with a temperature variation of (and here) 3 deg C. The laser system is to maintain position over the course of a day as well as repeat the same position within 30 minutes of turn-on on a day-to-day basis. The laser system must use real time monitoring and feedback to a fine motion control system (such as piezoelectric transducers). l. The Flashlamp. Changing the Flashlamp should not require the remo! val of the pump chamber from the laser head. Removing the pump chamber assembly to change the Flashlamp increases the chances of misalignment and contamination of the Nd:YAG rod surfaces. Also, the Flashlamp must have color-coded lead wires on designating the anode and cathode ends to decrease the chance of installing the Flashlamp backwards. And lastly, the Flashlamp lifetime should be greater than 40 million pulses to 90 percent of IR power. m. Trigger. Advanced sync pulse generator must provide a pre- or post-trigger pulse with respect to the Q-switch in the range positive 500 nanosec to negative 700 nanosec. This will provide a convenient pre- or post-trigger pulse with a range of 0 to 500 nanosec with respect to the output pulse. n. Computer interface. PC-based graphical interface software for control of tuning system. The OPO system must be fully automated including scanning capability. The OPO system must include auto-tracking feedback loops to the tuningcrystals that can be used to automatically write the standard look-up tuning tables. The remote module must display both signal and idler wavelength readouts and the have the capability to pre-program several common automated scan ranges. It also must include full-function remote control module with optional RS-232 /IEEE-488 interface capability. o. The OPO cavity. The OPO cavity must incorporate an unstable resonator design (Unstable Resonator refers to a patented cavity design, not output stability). This design ensures good beam quality and low divergence, hence the ability to focus to diffraction limited spot sizes. The design also provides the highest frequency conversion efficiency thus eliminating the need to for potentially damaging high pump fluence. q. The OPO crystal. The OPO crystal must be hard-coated crystal to negate the need for temperature stabilization. Hard-coated, sealed crystals are protected from moisture and environment without heating. ! r. OPO Beam Quality. The OPO beam profile must be round, not elliptical. Graphical content must be provided showing the roundness of the beam profile. s. Auto-tracking. The system must have feedback loops that automatically track a small portion of the output of the master oscillator and power oscillator and optimizes the crystal angles to peak the power (while scanning and while static). This auto-tracking system ensures optimum performance independent of environmental changes (temperature, etc.). Also, the photodiodes that monitor the output of the master oscillator and power oscillator will provide relative output energies that will be used as a diagnostic. t. Infrared Frequency Mixing. The IR extension system will provide the capability for an external frequency mixing system which can be tuned from 1800 nm to 4200 nm. This system will automatically interface with the OPO for ease of tuning. u. The laser system must have some degree of ease of use and ease ! of transport. For example, the laser system uses standard Nd:YAG crystal rods for ease of maintenance and replacement and the laser head must have detachable umbilical for ease of transport. The required items and quantities are: Nd:YAG PRO 230-10 with MOPO-SL; quantity: 1. Required delivery is within 30 days after date of order under F.O.B. Destination terms.
