Abstract

A short, telescopic laser resonator design is proposed for high-power, single-transverse mode emission from a lens shape composite solid-state laser. Such a laser combines the simplicity of the edge-pumped thin disk laser with the great advantage of axial heat flow in a very thin, below 50 m, active media thickness. The efficiency, output power and conditions of the single transverse mode oscillation are analyzed. For a device of a few millimeters wide, the slope efficiency of 49% and the threshold of a few watts are predicted. The possibility of output power of kW level is analyzed..
