Abstract:
A method for expanding a tuning range of an all-solid-state continuous-wave single-frequency laser is provided. The method includes inserting a nonlinear frequency-doubling crystal into a laser resonant cavity, and converting a part of intra-cavity fundamental-frequency light to frequency-doubled light by the nonlinear frequency-doubling crystal, outputting the generated frequency-doubled light and the fundamental-frequency light together from the laser resonant cavity, and separating the two via a spectroscope. The method also includes splitting a part of the fundamental-frequency light reflected by the spectroscope through an optical beam-splitter, and outputting the remaining part of the fundamental-frequency light as a main laser. A cavity length of the laser resonant cavity is changed by adjusting a voltage loaded on a piezoelectric ceramic of the all-solid-state continuous-wave single-frequency laser, thereby achieving continuous frequency-tuning of the all-solid-state continuous-wave single-frequency laser.
