Performance of efficient Q-switched diode-laser-pumped Nd:YAG and Ho:YLF lasers for space applications [PDF]
Solid-state lasers pumped by continuous-wave diode lasers can be Q-switched to obtain high peak power output pulses. The dependence of laser-pulse energy, average output power, peak power, and pulse width on pulse-repetition frequency in Q-switched Nd ...

DIODE PUMPED 2- μm Holmium Laser
Advanced Solid State Lasers, 1986 A high efficiency laser diode array pumped Nd:YAG solid state laser has recently been demonstrated.1 We report for the first time a diode array pumped rare-earth laser other than Nd. Laser action was observed on the trivalent Holmium 5I7→5I8, 2.1 μm transition. Laser sources in this wavelength region are required in infrared optical fiber communication

Advanced Optical Materials, EarlyView.A dual‐domain PSLC architecture enables direct comparison of alignment‐dependent laser damage within a single device. Crack‐like and seal‐like morphologies emerge under different damage conditions, and their evolution is interpreted through quantitative image analysis and heat‐driven simulations.
