- Description
- NASA/GSFC plans to issue a Request for Quotations (RFQ)] for the following Commercial item: Statement of Work Specifications for a 25 Watt Argon Ion Laser System with Heat Exchanger: - Integral Heating Exchanger - Remote Control Module - Automatic Lasing Acquisition - Automatic Wavelength Training - Automatic Cavity Alignment - Automatic TEM00 Acquisition - Automatic Aperture Selection - Self-time Exposure - Sabre Sentry System - Interlockable Safety Shutter The Laser System and Heat Exchanger performance goals shall be as follows: LASER SYSTEM Output powers: Multiline Visible 25.0 watts 514.5 nm TEMoo 10.0 watts* 488.0 nm TEMoo 8.0 watts* Multiline UV 7.0 watts 351.1 nm TEMoo 1.8 watts* 363.8 nm TEMoo 1.7 watts* *Mode quality index (M2 )* 1.1 Long term power stability: ?0.5% in light regulation mode (measured over 8 hours) ?1.0% in current regulation mode Optical noise: 0.2% RMS in light regulation mode 0.2% RMS in current regulation mode Beam Diameter: 1.9 mm @ 1/e2 points Beam Divergence: * 0.4 mrad (full angle) Beam Pointing Stability: <5 ?rad/?C angle change <5 ?m/?C beam offset change - Input power requirements cannot exceed 70 Amps, 480 VAC(3 phase). System must be capable of operating with a ?10% fluctuation in input voltage. - Cooling water for the laser head and power supply are to be provided from a closed loop heat exchanger. Performance specifications for the heat exchanger are listed below. - Plasma tube is to be of metal disk bore/ceramic envelope construction providing drop-out free operation and uniform gas distribution within the plasma tube. The ceramic is to consist of one piece and contain no frits, welds, or brazes. - Plasma tube shall have the output coupler sealed directly to the plasma tube to eliminate absorption of plasma UV in the anode window, which results in premature tube failure. - System is to be supplied with RS-232C interface to allow its use with laboratory computers. - Laser is to be supplied with a remote control module located on the end of a 15 foot cable. Included in this remote control module is to be a simultaneous digital display of output power, operating mode (light or current regulation), operating wavelength, transverse mode status, and plasma discharge current level. The remote control module shall also provide latching fault diagnostic displays and all controls necessary to operate and monitor the laser and heat exchanger. - Remote control module is to contain provision to allow the user to immediately (<1 sec), repeatably, and reproducibly switch back and forth between 1 watt multiline output and 25 watt multiline output in both light and current regulation modes. Using RS-232 interface, system shall be capable of switching between 10 different power settings. - Laser shall be able to automatically align itself to a lasing condition from a non-lasing condition with no requirement for the user to open the laser head cover or align cavity mirrors. - Laser shall be able to automatically tune to individual laser wavelengths as directed by the operator. When wavelengths are changed, the laser shall automatically recalibrate the power detection photocell to the new wavelength to optimize operation. - Laser shall be able to automatically realign both cavity mirrors to optimize cavity alignment and achieve maximum output powers. - Laser shall have a detector that monitors mode-beat noise and is capable of determining when TEMoo (M2 * 1.1) operation of the laser has been achieved. - Laser shall be provided with an intracavity aperture to allow control of the transverse mode of the laser. This aperture shall be motor-driven and controlled from the remote control module. Operator shall be able to select individual aperture sizes, select TEMoo operation, or select the closed position. If TEMoo operation is selected, laser is to automatically set the aperture to the size that acquires TEMoo at the highest possible output power. If the closed position is selected, the intracavity beam shall be interrupted and lasing prevented. - Laser shall have an integral shutter that is located outside of the laser cavity and is capable of blocking the output beam without interrupting lasing. This shutter is to be controlled from the remote control module to allow its opening and closing. This shutter shall have the capability of being used with a safety interlock system such that when the door to the laboratory is opened, the shutter will close and block the laser beam. - This laser shall provide self-timed exposures without the need for any external control device. User shall be able to set exposure times on the remote control module from 0.1 second to 3250 seconds in 0.1 second increments. - To allow integration into the experimental configuration, laser head width cannot exceed 8.00". - The plasma tube Brewster window must be of hard sealed crystalline quartz to prevent color center formation due to plasma UV degradation which results in premature failure of the plasma tube. - Laser system is to utilize an automatic gas pressure monitoring and filling system to maintain optimum plasma tube pressure. HEAT EXCHANGER - Heat exchanger is to be capable of transferring 60 kW of heat from the laser system secondary cooling water loop to the primary water supply. - Heat exchanger must regulate the secondary cooling water temperature to ?1?C. - Heat exchanger is to be interfaced with the laser system for power and control. Heat exchanger will automatically be turned on when laser is turned on, and shall continue circulating water in the secondary cooling loop for a period of 5 minutes after laser system is turned off, at which time the heat exchanger will turn itself off. - Heat exchanger must display the temperature, water flow rate, and resistivity of the secondary cooling water loop on the laser remote control module to allow the operator to monitor critical cooling water parameters. - Heat exchanger must shut down the laser in the event that water flow drops below allowable levels, cooling water temperature rises above allowable levels, or resistivity of secondary cooling water drops below allowable levels. Proposals will be evaluated based on a combination of technical and price. Adjectival ratings ranging from excellent to poor will be used in the evaluation of proposals. Award will be made to the offereor that represents the best value to the government. The anticipated release date of RFQ NNG05105012Q is on or about 05/11/2005 with an anticipated quotation due date of on or about 05/27/2005. All responsible sources may submit a quotation which shall be considered by the agency. An ombudsman has been appointed. See NASA Specific Note "B".
