Paper Abstract

We report the development of a very compact, highly efficient, megawatt peak power 266 nm UV microlaser. It contains a specially designed passively Q-switched Nd:YAG/Cr4+:YAG microchip laser whose high output peak power of 13 MW enables us to perform wavelength conversion without using any optics before the nonlinear crystals. We achieve 73 % SHG conversion efficiency using a LBO crystal and 45% FHG conversion efficiency using a BBO crystal. As a result, we obtain 650 μJ, 4.3 MW peak power, 150 ps, 100 Hz pulse output at 266 nm. This palm-top size 266 nm UV microlaser will be useful for many applications.
