✦ Synopsis

A single Xe gas filled flash lamp has been used to pump a Nd-doped SGGM rod 5 mm in diameter and 80 mm in length. Laser emission has been observed at 1.06 gm in the free running mode of operation in the input energy range of 1-25 J. The laser performance has been evaluated using two different diffuse/filter combinations to block the ultraviolet radiation from the Xe lamp and the results have been compared. The intrinsic slope efficiency was determined to be approximately 1.5% with an 80% output coupler and a spectralon diffuser.

Recent years have seen considerable interest in the development of compact "all-solid-state" lasers pumped by diode lasers. Diode lasers operating in continuous wave (cw) and/or pulsed mode at a wavelength A = 8 1 0 + 5 nm with output powers ranging from a few watts to kilowatts per cm 2 are commercially available. Nd-doped host materials have been pumped and laser emission at 1.06 ~tm
