摘要：

We have demonstrated cw diode end pumping of Nd:KGW, a novel solid-state gain medium, with rip to 30% conversion efficiency into near-TEM(00) (M(2) < 1.05) output at lambda = 1.067 mu m for a pump level of 2.7 W. The slope efficiency was limited by intracavity reflections to 36%; however, direct comparison to a similar Nd:YAG laser indicates the same intrinsic slope efficiency of approximate to 60%. FM mode locking of this laser at 200 MHz: has produced 12 ps pulses (compared to 16 ps for Nd:YAG), although an intracavity etalon was required. Considerable reduction in pulse width is possible (the line width limit is approximate to 0.5 ps) but different techniques may be necessary. Spatial hole burning was evident in both the approximate to 120 GHz free-running spectrum and the etalon-limited mode-locked spectrum.
