Low-cost scanning MEMS micro-mirrors were incorporated within the cavities of Nd:based laser systems to control the output beam characteristics. Successful Q-switching was obtained from these solid-state intra-cavity MEMS lasers resulting in pulse durations of 220 ns and peak powers of 13.2 W at a wavelength of 1064 nm.
An intracavity deformable membrane mirror has been used to control the transverse mode profile of a diode-pumped, grazing-incidence Nd:GdVO/sub 4/ laser. Automatic mode and power optimisation are demonstrated using a closed-loop genetic algorithm.
