E-MAIL: B. Terry Cobb, t.g.cobb@larc.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). Specifications for Conduction Cooled QCW Laser Diode Arrays: 2 EACH The laser diode arrays will be used to end pump Nd:YAG laser disks. The arrays will be used in a research laboratory environment. The quasi-cw laser diode arrays shall be a completely operational system consisting of stacks of linear array bars with a micro lens mounted for each bar to collimate the laser emission and having surface/s for conductive cooling. Each quasi-cw array shall meet the following specifications: A) The diode array bars must contain an aluminum-free active area. B) The linear array will consist of 2 stacks of 30 bars each. The separation of the 2 stacks will be 0.8mm. The bars of each stack shall be mounted with a pitch of 0.8mm10.005mm. No 2 adjacent bars in the array shall be unlit. C) The arrays shall each contain 60 bars on a 0.8mm pitch (bar spacing center to center). The emitting aperture of the diode array shall be 23.2mm x 21 mm. D) Each bar shall be rated at least 100 watts peak power (before lensing). E) The total peak power output before lensing shall be at least 6000 watts and 4500 watts after lensing. F) Beam divergence of the fast axis (perpendicular to the active region) shall be less than or equal to 30. Slow axis divergence (parallel to the active region) shall be 100. The collimating micro lenses should be aligned parallel to the diode array bars with a high degree of accuracy such that >95% of the laser power is captured in a bucket the size of 2.2" at 3 feet from the diode array. The diode array stack will be used with a lens duct whose transmission efficiency drops sharply if the micro lenses are misaligned or tilted with respect to the diode array bars. The micro lenses must be installed such that the collimated output from each array is parallel in the near field. G) The center wavelength of the array shall be 80713 nm at 200C heat sink temperature for the specified pulse length of 200 microsecond, 10 Hz repetition rate at full power. H) The spectral bandwidth of the array shall be < 3 nm FWHM at full operating current. I) The electrical to optical conversion efficiency with the collimating optics shall be nominally 35%. J) The maximum pump current shall not exceed 120 Amperes at full power operation. K) The array compliance voltage shall not exceed 140 volts. L) The array threshold current shall not exceed 25 Amperes. M) Lifetime of the diode arrays shall be at least 1x109 pulses guaranteed with no more than 5% degradation in laser output power when operated at 200 microsec pulse width, 10 Hz repetition rate, and 200C package temperature at full power. N) Laser bars shall be tested for 24hours at the average operating cycles, defined by the supplier, before being combined into the array package to avoid infant mortality. O) The diode array shall have 8" stranded leads. P) The vendor shall include a data package, which shall contain the following: 1) Power output as a function of current at specified pulse length of 200 microsec, 10Hz pulse repetition rate, and 200C heat sink temperature to full power. 2) Voltage as a function of current at specified pulse length of 200 microsec, 10Hz pulse repetition rate, and 200C heat sink temperature to full power. 3) Spectral emission at specified pulse length of 200 microsec, 10Hz pulse repetition rate, and 200C heat sink temperature to full power. 4) A diagram showing array dimension, electrical and conduction cooling interfaces.
