Paper Abstract

An experimental studying of Nd:YAG rod side-pumping with quasi-cw-laser-diode bars as a function of the laser rod and the pumping sub-mount parameters was carried. We have found that the side-pump-of-rod geometry without coupler optics between the laser diodes and the laser rod provides sufficiently high slope and optical efficiencies of Nd:YAG laser. Utilizing the concentric pumping arrangement with eight laser diode bars maximum optical efficiencies of 50% and 45% in long pulse mode was obtained when 5mm and 4mm diameter Nd:YAG (1.2% at) rods respectively were used. In Q-switched operation Nd:YAG laser with this pumping scheme and 5mm diameter (1.2% at) rod had an output of 23 mJ in multimode 10 ns pulse when output coupler was of 60%.
