10 W-level sub-100 ps 1 MHz MOPA laser with a microchip master oscillator

A 10 W level master oscillator power amplifier (MOPA) laser with pulse repetition rate up to 1 MHz and 75–95 ps pulse duration was developed based on a passively Q -switched N d : Y V O 4 microchip 1064 nm laser as a master oscillator. A double-rod double-end-pumping configuration of two-pass Nd:YAG...

Description
Summary:A 10 W level master oscillator power amplifier (MOPA) laser with pulse repetition rate up to 1 MHz and 75–95 ps pulse duration was developed based on a passively Q -switched N d : Y V O 4 microchip 1064 nm laser as a master oscillator. A double-rod double-end-pumping configuration of two-pass Nd:YAG ring power amplifier was used to achieve high gain, near-Fourier-transform-limited pulses, and laser beam quality factor M 2 = 1.27 along both the horizontal and vertical directions.
