Laser Jamming in the 3 to 5 microns Wavelength Band
Abstract
The generation of 3 to 5 microns laser radiation and the required powers to jam IR-seekers were investigated in relation to a laser-jamming system. Sufficient powers were reached with two generation methods. The first method used difference frequency generation (DFG) to obtain 4.04 microns radiation using the mixing in LiNbO3 of 1.064 microns and 1.444 microns radiation, which were obtained from two Nd:YAG lasers. The second method used an OPO of BBO to generate tunable radiation around 1.4 microns that was used in the DFG setup to generate tunable 3 to 5 microns radiation. Measurements of the damage threshold of photodiodes confirmed the theoretical considerations that state that the order of magnitude of the damage threshold is 1 J/sq cm.
