Uniform Diode-Pumping by a Highly-Diffuse with Cross-Axis Beam Delivery Side-Pumping System. The HiDiCAD Cavity

摘要

A new cavity for diode side-pumped solid-state lasers was designed, built and tested. The results of which were an efficient absorption of the pumped light in the media and homogeneous pump-beam distribution under various pump-power levels, Nd:YAG active media of different radii and concentration and shifts of the diode wavelength resulted. Single transverse mode operation (laser beam M~2 factor less than 1.1) of 163 W was demonstrated.
