Abstract :
CuBr master oscillator-power amplifier (MOPA) laser system fitted with a generalized diffraction filtered resonator (GDFR) is reported to produce high-quality beam of throughout-pulse diffraction-limited laser emission at the repetition rate of ∼19 kHz. The comparison with typical (stable and unstable) resonator configurations for CuBr lasers has featured out its high brightness accompanied by a very low beam divergence permanent within laser pulse. This intrinsic characteristic of GDFR-MOPA laser radiation makes it a perfect light source for fine laser applications.
