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.
Intracavity low-cost scanning MEMS micromirrors are used to control the output beam of Nd:based lasers. Successful Q-switching resulted in pulse durations of 200ns.
This paper will give further results obtained from introducing electrothermal and electrostatic MEMS within laser cavities with particular attention given to the thermal effects of the micromirror, and new modulation/control prospects. The exploitation of the MEMS devices in solid-state lasers operating at 1.5mum will also be described.
