TLDR
In this paper, a Q-switched microchip laser emitting radiation at wavelength 1338 nm was designed and constructed based on a monolith crystal which combines in one piece a cooling undoped part (undoped YAG crystal), an active laser part (Nd3+:YAG, T0=85%), and a saturable absorber.Abstract:
Q-switched microchip laser emitting radiation at wavelength 1338 nm was designed and constructed. This laser was based on a monolith crystal which combines in one piece a cooling undoped part (undoped YAG crystal), an active laser part (Nd3+:YAG), and a saturable absorber (V3+:YAG, T0=85%). The microchip resonator consists of dielectric mirrors directly deposited on the monolith surfaces. The output coupler with reflection 90% was placed on the V3+-doped part. Q-switched microchip laser was tested under pulsed, and CW diode pumping. The pulse length was the same for all regimes and it equals to 6.2 ns. The wavelength of linearly polarized laser emission was 1338 nm. For pulsed pumping the output pulse energy was stable up to mean pump power 1 W and it was equal to 131 μJ, which corresponds to peak power 21 kW. In CW regime for pumping up to 14 W the pulse energy was 37 μJ.read more

Analytical and experimental studies on the characteristics of composite solid-state laser rods in diode-end-pumped geometry
Abstract: In this paper, we report analytical and experimental studies on the characteristics of end-pumped composite laser rods with undoped end, using mainly Nd:YAG rods as an example. It is found that the peak temperature rise in a composite rod decreases to <70% of that in a noncomposite crystal. Thermal stress is dramatically reduced to <60% by employing the composite rod structure, We also demonstrate high-power operation of the diode-end-pumped composite Nd:YVO/sub 4/ rod and a maximum CW output power of 9.3 W was achieved, which is about 1.5 times higher than that in the noncomposite rod. This high-power performance of the composite rod is primarily attributed to the reduction of thermal stress inside the rod.
