Use of Intracavity Adaptive Optics in Solid-State Lasers Operation at 1 µm

  • Conference paper
Adaptive Optics for Industry and Medicine

Part of the book series: Springer Proceedings in Physics ((SPPHY,volume 102))

Summary

An intracavity 37-element deformable membrane mirror (DMM) has been used in order to control the transverse mode profile of a diode-pumped solidstate laser. Automatic spatial mode and output power optimisation of Nd:YVO4 end-pumped and Nd:YAlO side-pumped lasers are demonstrated using a closed-loop genetic algorithm. Transverse mode and power optimisation of a diode-pumped, grazing incidence Nd:GdVO4 laser has been performed successfully. The optimisation procedure featured a genetic algorithm ensuring the global maximum is attained. Using a Michelson interferometer with the DMM operating intracavity, the DMM was found to present negligible deformation when used with a power density of 115W/cm2 but noticeable deformation appeared with a power density of 1.25 kW/cm2.
