Influence of temperature of a second harmonic crystal on the power stability of intracavity frequency-doubled diode pumped Nd:$YVO_4$ lasers

비선형 광학 결정의 온도가 다이오드 레이저 펌핑된 내부 공진기형 Nd:$YVO_4$ 이차 조화파 레이저의 출력 안정도에 미치는 영향

Intracavity second harmonic generation of diode pumped solid state lasers in the visible and ultraviolet regions provide efficient, compact and robust light sources for various applications, such as optical data storage, material processing, spectroscopy and bioanalysis. Advantages of neodymium vanadate (Nd：$YVO_4$) as a gain medium for intracavity-doubled lasers over Nd：YAG lie in the facts that the gain spectrum consists of a single line with short absorption depth, and that the stimulated emission cross sections are larger.
