Efficient continuous-wave generation in a self-organizing diode-pumped Nd : YVO4 laser with a reciprocal dynamic holographic cavity

摘要

A diode-pumped Nd:YVO4 laser is demonstrated that has a reciprocal self-intersecting loop cavity with self-organization by formation of a dynamic holographic grating induced by the generating beam. Continuous-wave high spatial quality generation (M-2 < 1.2) with 9.6 W of power and 32% optical efficiency is obtained. Spectral compositions and temporal dynamics are investigated as functions of diode-pumping power. (C) 2004 Optical Society of America.
