Paper Abstract

Performance requirements for laser sources, operating in the mid-IR, providing protection of airborne platforms from heat-seeking missiles are reviewed. The critical performance characteristic for a countermeasures laser is 'useful energy on target', which requires the laser to generate high brightness output in the appropriate spectral bands with rapid turn-on time. Integration with a compact beam director places an upper limit on the beam quality of the laser output. The key driver for the detailed laser design is to maximise the overall wallplug efficiency in order to minimise the complexity and volume, in turn maximising the reliability and reducing the cost. In particular routes to reduce the thermal management system for the laser produce the single largest improvement in overall wallplug efficiency, with the ultimate goal of realising a truly athermal laser. Candidate technologies for IR countermeasures lasers are briefly reviewed.
