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 (OPO) to a pump laser source, it is possible to cover the 2-5 μm wavelength transmission windows. After a risk reduction phase of five years, CILAS has designed a solid state laser source (SSLS) adapted for DIRCM jamming and has delivered a prototype to DGA-MI for testing and evaluation. The purpose of this paper is to recall the requirements of such a laser source, to present the main design trade-off and the testing experiments. This work is supported by the French MoD (DGA).

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).
