Paper Abstract

It is theoretically and experimentally demonstrated that Gaussian reflectivity mirrors (GRMs) can improve the performances of lasers for radar applications. The effects of misalignment and hard apertures are investigated. The optimum design parameters are given. Single mode operation of a TE-CO2 laser was obtained in a Cassegrain resonator made of a hard concave mirror and a convex mirror with a Gaussian reflectivity profile. The 70-nsec pulses (FWHM) had an energy of 175 mJ, a peak power of ≈ 2.0 MW, a near diffraction limited far field and a chirp rate smaller than .060 MHz/μsec2.
