Generation of high-power nanosecond pulses from laser diode-pumped Nd:YAG lasers
Simulation results are used to compare the pulse energy levels and pulse energy widths that can be achieved with LD-pumped Nd:YAG lasers for both the pulse-transmission mode (PTM) and pulse-reflection mode (PRM) Q-switching methods for pulse energy levels up to hundreds of microjoules and pulse widths as short as 1 ns. It is shown that high-power pulses with pulse widths as short as 1 ns can be generated with PTM Q-switched in LD-pumped Nd:YAG lasers. With the PRM Q-switching method, pulse widths as short as 2 ns and pulse energy at the level of a few hundred microjoules can also be achieved but require pumping with 8-10-mJ AlGaAs laser diode arrays.

Multiple-pass laser-diode-pumped Nd:YAG amplifier - Design
A method for designing a miniature laser-diode-pumped Nd-YAG laser amplifier based on total internal reflection and a multiple-pass slab geometry is described. This new design leads to a simple and practical configuration which allows multiple-pass amplification to be accomplished fairly easily by utilizing an optical arrangement with external mirrors. It is suggested that this type of miniature Nd-YAG amplifier combined with a laser diode-pumped Nd:YAG oscillator could result in an excellent laser-ranging source laser.
