Efficient second-harmonic generation of a diode-pumped c-w Nd:YAG laser using an externally resonant cavity
Diode-pumped solid-state lasers are efficient and compact sources of coherent IR radiation, but for many applications short-wavelength visible sources are desired. Intracavity frequency doubling is a proven method of efficient conversion of these lasers to the visible, but generally results in deeply amplitude-modulated output. An alternative approach is external cavity frequency doubling to provide stable single-axial-mode output at the second harmonic. The authors used external-cavity frequency doubling to generate 56% second-harmonic conversion efficiency of a 53 mW, cw, diode-laser-pumped Nd:YAG oscillator. A monolithic cavity of MgO:LiNbO3 resonant at the fundamental was used to generate the 30 mW of single axial mode 532 nm radiation.
