Compact architecture for power scaling bounce geometry lasers.
We demonstrate the compact high-power scaling of bounce geometry lasers with a new dual-pumped folded amplifier design. A Q-switched laser oscillator built with this amplifier is shown to produce over 30 W of average power from 80 W of pump power at up to 600 kHz repetition rate. In a master-oscillator power-amplifier (MOPA) configuration using the dual-pumped amplifier, we demonstrate over 100 W of output power from 250 W of pump power. We also demonstrate very high repetition rate Q-switching (1.7 MHz) of the master oscillator.
