Laser Target Designator Beam Improvement.

reportActive / Technical Report | Accession Number: ADA007139 | Need Help?

Abstract:

Thermal focusing contributes to laser beam divergence which is a problem in the design of laser target designators. Measurements of the thermal focusing induced in a neodymiumyttrium aluminum garnet laser rod by input powers typical of target designators are described. The application of such measurements in the design of laser resonant cavities is illustrated.
