E-MAIL: Timothy P. Stubbs, T.P.STUBBS@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; offers are being requested and a written solicitation will not be issued. This procurement is being issued under the authority of FAR Subpart 13.5, Test Program for Certain Commercial Items. This notice is being issued as a Request for Offer (RFO) for Conductivley-Cooled Laser Diode Arrays (LDAs). The LDAs will be used to side pump Ho:Tm:YLF solid state laser rods. The arrays will be housed in a laser head that will incorporate the arrays, a laser rod, and a flow tube. The laser head that accommodates the arrays has a region no greater than 1/2 inch wide, 1/4 inch high, and 1 inch deep, excluding electrical lead connections reserved for each array. The laser head is designed for the array's emission to be in a direction parallel to the centerline axis of the region's width while the electrical lead connections are at the end opposite from the array's emission end. The thermal transfer interface connection of the laser head is designed for mounting the array by two screws. The array systems will be used in a research laboratory environment. The specifications for the LDAs are as follows: (A) The array shall be based on AlGaAs/GaAs laser diode technology. (B) The array package, excluding electrical lead connections shall be no greater than 1/2 inch wide, 1/4 inch high, and 1 inch deep. (C) The array package, excluding electrical lead connections shall have a mounting surface for heat transfer of no greater than 1/2 inch in width and 1 inch in depth. (D) The array package shall have 2 screw clearance holes for mounting located on the centerline axis of the package's width with 1 of the 2 clearance holes located no closer than 1/5 inch from the array's emission end. (E) The array package shall have its emission in a direction parallel to the centerline axis of thepackage's width. (F) The array package shall have electrical lead length connections of at least 1 inch located at the end opposite to that of its emission end. (G) The array shall be an operational system comprised of six bars stacked with conductively cooled surfaces. (H) The array shall contain six bars on a pitch of 0.4 mm (bar spacing center to center). (I) Each bar shall be rated for at least 100 watts peak output power. (J) Total peak output power per array shall be at least 600 watts. (K) Center wavelength shall be 792 +/- 3 nm at 20 degrees C heat sink temperature for specified pulse length of 1 millisecond (ms), 10 Hz repetition rate at full power. (L) Spectral emission bandwidth shall be 4.5 nm full width half maximum (FWHM) or less for specified pulse length of 1 ms, 10 Hz repetition rate, 20 degrees C heat sink temperature at full output power. (M) The array shall be capable of operating at a pulse length of one millisecond. (N) Duty factor shall be less than or equal to 1.3 percent. (O) Lifetime of the diode arrays shall be at least 2.5x108 pulses guaranteed with no more than 5 percent degradation in laser power output for operation at a pulse length of 1 ms, 10 Hz repetition rate, at 20 degrees C heat sink temperature at full output power. (P) Laser bars shall be tested for at least 100 hours at the average operating cycles defined by the supplier to avoid infant mortality. (Q) The operation of the laser diode arrays shall be: [1] Wavelength: 792 +/- 3 nm; [2] Peak Output Power: 600 Watts; [3] Operating Temperature: 20 degrees C heat sink temperature; [4] Pulse length: 1.0 ms; [5] Pulse Repetition Frequency: 10 Hz (Maximum of 13 Hz). (R) Shall include a data package, which shall contain the following: [1] Output Power as a function of current at specified pulse length of 1 ms and duty factor of 1.0 percent at 20 degrees C heat sink temperature to full output power value. [2] Voltage as a function of current at specified pulse length of 1 ms and duty factor of 1.0 percent at 20 degrees C heat sink temperature to full output power value. [3] Spectral emission at pulse length of 1 ms, 10 Hz repetition rate, and at 20 degrees C heat sink temperature at full output power. [4] A diagram showing array dimensions, electrical and conduction cooling interfaces. The provisions and clauses in the RFO are those in effect through FAC 97-11.
