Bleachable Absorber Laser Amplifier and Detector: BALAD

Abstract

The report describes the continued development of the wide-angle, low noise BALAD receiver (Bleachable Absorber Laser Amplifier and Detector). A xenon-xenon 3.5 micrometer BALAD receiver system has been tested. Experimental results are given. The experiments were hampered by excess noise in the xenon absorber discharge. The three dimensional analysis of the propagation of coherent optical pulses with limited transverse extent, predicts a non-linear self-focussing effect. A modified design of the BALAD receiver using a geometrical loss filter based on this effect is presented and analyzed. The design would facilitate the rejection of noise from the other laser amplifier transitions.
