Paper Abstract

We report on the development and characteristics of infrared solid state laser as compact and robust light sources for Directed Infrared Countermeasures (DIRCM). DIRCM against infrared missile seekers requires wavelength tunable laser sources. When adding an optical parametric oscillator to a pump laser source, it is possible to cover the 2-5 μm wavelength transmission windows. For more than five years, CILAS has developed critical technologies for the development of a laser source adapted for DIRCM application. This includes: The choice of the crystals, the optical coatings in band II, the thermal management and an optimized oscillator configuration insensitive to repetition rate variation in a wide range. The scope of this presentation is to recall performances of the technologies developed and to present the technical base line of our laser concept. This work is supported by the French MOD (DGA).
