Efficient cw end-pumped, end-cooled Nd:YVO4 diode-pumped laser

摘要

Using a novel end-pumped, end-cooled geometry, we demonstrated a Nd:YVO4 cw laser that produces close to 2 W of single-mode output when pumped by a high-brightness 100-mu m-core diode fiber source. An optical-optical conversion efficiency of 49% was obtained. Beam quality was found to be nearly diffraction-limited (M-2 = 1.08) and independent of pumping power.
