Abstract: The LAMPS module is a compact, back cooled, vertically stacked, two-dimensional, incoherent array of diode laser bars featuring all-soldered construction with partial collimation of the emitting diode laser light to form a laser power source that can be transformed into a laser line source of exceptional brightness. The array includes a diode laser unit which comprises a diode laser bar, an electrode, and a substrate soldered to a heat sink. The diode laser unit is joined by soldering to an electrical isolator plate, and the isolator plate is joined to a heat exchanger by soldering for removal of waste heat. The invention includes a method for forming the array and a heat exchanger for removing heat from the array.

Abstract: A laser doppler velocimeter with laser backscatter discrimination for determining the relative velocity between an optical platform and another target where a laser beam is generated and directed toward the target. A detector produces a doppler signal in response to the detection of the laser beam. Noise and backscatter signals with bandwidths and amplitudes outside selected thresholds are rejected, and the legitimate doppler signal from the target is enhanced.
