A compact laser-diode dual-end-pumped 3 at. % a-cut Tm:YAP InnoSlab laser with the output power of 254 W in 1.99 µm has been demonstrated. The slope efficiency with respect to the incident pumped power is 45.9%, and the optical-to-optical conversion efficiency is 36.5%. The RMS stability of the maximum output power is better than 0.1% in 30 min. Beam quality factors are 250 in the direction and 4.7 in the direction. Additionally, the shape of the output laser spot is rectangular.

Based on the theoretical and experimental investigations of the influences of ETU and ESA effects on laser performance, a high power CW TEM Nd:YVO 1.34 μm laser dual-end pumped at 880 nm was achieved with a maximum output power of 16 W.

A Nd:YVO4 crystal consisting of three segments with different doping concentrations is originally developed for power scaling in diode-end-pumped solid-state laser. We systematically make a comparison of laser characteristics between the multi-segmented and conventional composite crystals to show the feasibility of using gain medium with multiple doping concentrations for power scale-up in end-pumped laser without introducing significant thermally accompanied effects. We further construct a dual-end-pumped actively Q-switched oscillator at 1064 nm to verify the usefulness of our crystal design, where the largest pulse energy of 1.

An efficient 2 μm in-band pumped Ho:YAG laser was demonstrated. The resonator involves two Ho:YAG crystals, each of which was dual-end-pumped by two orthogonally polarized diode-pumped Tm:YLF lasers. The maximum continuous wave output power of 103 W was achieved, corresponding to a slope efficiency of 67.
