52-mJ, kHz-Nd:YAG laser with diffraction limited output

We present Nd:YAG, diode pumped amplifier system emitting up to 52-mJ pulse energy with 1.6-ns pulse duration and near diffraction limited beam, operating at 0.75-kHz repetition rate.

Self-seeded, Single-frequency Nd:YAG Q-switched Micro Laser with 1.7-ns, 1-mJ pulses at 1 kHz

We report on passive Q-switching of a Tm,Ho:LiYF4 laser with Cr:ZnSe saturable absorber achieving for the first time short (~50 ns) pulse durations and high (~640 W) peak power from such a diode-pumped Ho-laser.

High average power, kilowatt bursts of 6 ps pulses

In this work, we report the amplification of laser pulses from a near diffraction limited, passively Q-switched Nd:YAG master oscillator (0.58 mJ, 1.2 ns at 0.5 kHz) up to 52-mJ in a Nd:YVO4 preamplifier and two diode pumped boost YAG-amplifiers, whilst preserving pulse duration, beam quality and linear polarization.
