High-power periodic-pulse YAG:Nd3+-laser system with telescopic unstable resonator and two-stage amplifier
Abstract
A high-power YAG:Nd (3+) laser system is described which incorporates a master oscillator with an unstable telescopic resonator, polarizational radiation dumping, and a two-stage amplifier. Energetic, temporal, spectral, and spatial characteristics of the master oscillator are studied as well as those of the system as a whole. The system makes it possible to generate radiation pulses with a power greater than 70 MW upon divergence close to the diffraction limit and a pulse repetition frequency of 10 Hz.
