- Contracting Office Address: Department of Commerce, National Institute of Standards and Technology (NIST), Acquisition Management Division, 100 Bureau Drive, Building 301, Room B129, Mail Stop 1640, Gaithersburg, MD, 20899-1640 Background: The National Institute of Standards and Technology (NIST) seeks information on commercial vendors that are capable of providing a tunable, single-frequency Ti:sapphire laser system. NIST's The Optical Spectroscopy of Nanomaterials Project, within the Nanoelectronics Group in the Physical Measurement Laboratory intends to use this for resonant Raman spectroscopic studies of novel quantum nanomaterials at varying temperatures and magnetic/electric fields. Wavelength tunability, stability and narrow bandwidth of this laser are crucial because Raman scattered photons are only different from the laser excitation by ~0.13 nm. High power is required because the output must be sent through multiple optical systems to deliver the light to mapping stages and/or cryostats located meters away. After market research results are obtained and analyzed, minimum requirements specifications for the tunable, single-frequency Ti:sapphire laser system will be established. NIST may use these established specifications in conducting a competitive procurement and subsequently award a Purchase Order in the future. If a minimum of two (2) qualified small businesses are identified during market research stage, then any resulting competitive procurement may be considered for a small business set-aside. Requirements: NIST is seeking responses from all responsible sources, including large, foreign, and small businesses. Small businesses are defined under the associated NAICS code for this effort, 334516, as those domestic sources with 1,000 employees or less. Please include your company's size classification and socio-economic status in any response to this notice. Product Requirements: The Contractor shall provide the following one (1) tunable, single-frequency Ti:sapphire laser system that meet the following minimum specifications: 1.Laser system shall consist of a connected Ti:sapphire ring cavity laser, a diode-pumped, solid state (DPSS) pump laser, an additional cavity for near UV, and all necessary electronics, hardware and software for operation of the system, including all chillers necessary for cooling. 2.Laser head shall be constructed of stainless steel and hermetically sealed with purge ports. a.Stainless steel critical requirement because the laser will be installed in a laboratory where varying levels of humidity will be present (20%-70%) and thus corrosion. Also, noticeable dust also accumulates in this laboratory. If the laser is not hermetically sealed, this level of humidity variation and possible dust contamination can cause unacceptable variations in laser performance. 3.Laser system shall be capable of producing output at any wavelength in the range 700 nm to 1000 nm AND the range of 350 nm to 500 nm. Additional value is given if the laser system can produce light from 690 nm. 4.Laser output power shall be at least 1 W at a wavelength of 532 nm. 1 W of power is required because of the distance and loss endured by the beam when directed into the cryostat and microscopic imaging platforms. 5.Laser system producing light from 700 nm to 1000 nm shall be fully automated and "hands-free", requiring no mechanical or optical changes or adjustments by the user. Furthermore, connectivity through TCP/IP is a critical requirement, since the system will be incorporated into a large, complex Raman facility. This instrument may be operated by users who are not laser experts and do not have the necessary knowledge and skills to adjust the laser on a regular basis. Providing the level of training needed for all users is unrealistic given the short duration of a typical collaboration. 6.Laser component for access to 300 nm to 500 nm must use a single set of optics and have conversion efficiency of >35% for 1 W of pump power. 7.Laser output in all ranges shall be single-frequency and continuously tunable. Single frequency laser output is required to carry out high resolution Raman spectroscopy where we look for small changes between the incident and scattered photons. Continuous tunability is required to complete full Raman excitation profiles (REP) which is our main exciton characterization method. 8.Laser output shall have an absolute free running linewidth of 100 kHz or less, measured over 100 us. It is critical that the free running wavelength be less than 100 kHz, since we are monitoring energy differences as small as 0.13 nm. This linewidth must be measured relative to an external reference, and not relative to the internal reference cavity, because the internal cavity could itself have errors or instabilities that would make this measurement inaccurate. 9.Laser beam shall be TEM00 with a Gaussian quality factor M2 of at most 1.2. This is critical because the output of the laser will be coupled through multiple optics into a confocal spot. If the M2 is greater than 1.2, power losses or heterogeneity in the beam center become unacceptable. 10.Laser output shall have at most 0.1% rms intensity noise, measured over 12 hours, including any long term drift in output frequency or intensity. This is a critical requirement. Amplitude noise and drift in the laser output translates directly into fluctuations. If the variation is higher than 0.1%, an unacceptable level of fluctuations will be present in the spectra, leading to unacceptable performance in imaging and unacceptable uncertainties. 11.Laser must include analog inputs and software/hardware control to enable wavelength adjustment and locking. Instruction to Responders: Companies that are capable of providing this tunable, single-frequency Ti:sapphire laser system are requested to email a detailed report describing their abilities to tracy.bisson@nist.gov no later than the response date for this sources sought notice. The report should include achievable specifications and any other information relevant to your product or capabilities. Also, the following information is requested to be provided as part of the response to this sources sought notice: 1.Name of the company(s) that offer the required supply. In addition, provide a point of contact for the company(s). 2.Indication of number of days, after receipt of order that is typical for delivery. 3.Interested vendors shall address their capability of providing Original Equipment Manufacturer (OEM) parts. 4.Any other relevant information that is not listed above which the Government should consider in developing its minimum specifications and finalizing its market research.
