58 -- CW LASER DIODE TRANSMITTER/RECEIVER MODULE SOL N68936-95-R-0324 DUE 071995 POC Alice Martin, Contract Specialist, (619) 939-4755/ Contracting Officer, Ted Fiske, (619) 939-8182. The Naval Air Warfare Center Weapons Division plans to procure the following: Quantity of One (1) each with Option for one (1) additional unit. CW LASER DIODE TRANSMITTER/RECEIVER MODULE which meets the specifications. 1) General Specifications - 45 degree forward look angle with respect to nadir (1/4 of a conic shell with a 45 degree vertex angle). Maximum receiver/transmitter aperature diameter is 1 inch. Receiver/Transmitter separation - 3 inches center-to-center (forward/aft). Mounting to support structure possible from rear to top of unit with aperture pointing down. 2) Transmitter - Continuous Wave (CW) Laser Diode with a 90 degree conic fan beam pattern, (1 degree shell thickness Modulated by an external or internal sine wave source, variable from 5 MHz to 120 MHz. Internal modulation source shall not drive laser power less than 3dB above the lasing threshold. Damage protection for laser diode against temperature or externally induced high current. 3) Receiver - Avalanche photodiode (APD) type: Field-of-View (FOV) aligned with the transmitter in crossed beam geometry. The receiver FOV completely overlaps the transmitter beam between the cut-on and cut-off ranges. FOV (total): 90 degree conic shell divided into 2 to 25 sectors, 12 desired, shell thickness determined by cut-on and cut-off ranges and signal-to-noise ratio (SNR). 4) Inputs (50 Ohms) - External modulation input. 5) Outputs (50 Ohms) - Modulantion Phase Reference: (monitor photodiode on laser). Transimpedance Amplifier output from each receiver sector. (The following desirable feature may or may not be exercised at time or award.) AMPLITUDE AND PHASE OUTPUTS FROM EACH RECEIVER SECTOR meeting the following specifications: This may be provided in the same enclosure or in a separate package with cable(s) to tramsmitter/receiver module. Complete specifications will be provided with the solicitation. Request for solicitation should be in writing to the above referenced address. All offers from responsible small businesses will be considered by the agency. See Numbered Note 1 (0152)
