Diode-pumped Nd:YAG/ KNbO_3 cw Blue Microchip Laser

摘要

A stable diode-pumped cw 473nm Nd:YAG/KNbO_3 blue microchip laser operating in fundamental transverse mode is reported. Intracavity-doubling was realized by using a KNbO_3 crystal cutted for type-Ⅰ phase matching at room temperature. The output characteristics of the microchip laser were investigated and the maximum blue output power was 25.7 mW with fundamental transverse mode. The laser proposed could operate in a relatively wider temperature acceptance bandwidth from 20℃ to 35℃.
