摘要：
High-power and high beam quality continuous-wave (CW) Nd:GdVO4 lasers operating at 1.34 mu m were experimentally demonstrated. The lasers consisted of either one or two crystals, which were both end-pumped by high-power fiber-coupled diode lasers. With one crystal, the maximum CW Output power generated was 8.4 W. When two crystals were used, a maximum Output power of 15.7 W was achieved with the incident Pump power of 76.2 W, showing a slope efficiency of 26.2% and an optical-to-optical efficiency of 20.6%. The beam divergence at an output power of 15 W was measured to be about two times that of the diffraction limit. Crown Copyright (c) 2008 Published by Elsevier Ltd. All rights reserved.
