The control of energy, temporal and spatial characteristics a microchip laser with active output mirror

Presented a results of the theoretical and experimental investigation of the Nd +3 :YAG microchip laser with passive Q-switch modulation based on Cr +4 . The laser operation is analyzed on the base of operator model of a microchip laser with an active output mirror based on Fabry-Perot interferometer. The experimental and theoretical results are in a good agreement. The feasibility of control over temporal and spatial characteristics of micro-chip laser radiation is demonstrated.
