Picosecond laser system based on microchip oscillator

We have developed a high-energy, compact, picosecond laser consisting of a diode-pumped, passively Q-switched microchip laser, and a flash-pumped two-pass Nd:YAG amplifier. Amplified pulses of maximum 19-mJ energy, 460-ps duration at (1-10) Hz rate, in a nearly TEMoo transversal mode at 1064-nm wave...

Description
Summary:We have developed a high-energy, compact, picosecond laser consisting of a diode-pumped, passively Q-switched microchip laser, and a flash-pumped two-pass Nd:YAG amplifier. Amplified pulses of maximum 19-mJ energy, 460-ps duration at (1-10) Hz rate, in a nearly TEMoo transversal mode at 1064-nm wavelength, were obtained. The infrared pulses were nonlinearly converted to 532-nm second harmonic and 266-nm fourth harmonic with a conversion efficiency of 50 % and 20 %, respectively.
