研究目的
To present a narrow linewidth, no-gain competition, 912 nm quasi-three level and 1064 nm four-level dual-wavelength laser for the first time.
研究成果
A narrow linewidth dual-wavelength laser with an F-P etalon was demonstrated, achieving linewidths of 0.284 nm and 0.627 nm at 912 nm and 1064 nm, respectively. The system effectively eliminated gain competition and is suitable for applications in laser medicine and optical communication.
研究不足
The technical constraints include the small absorption coefficient of the Nd:YVO4 crystal at 912 nm and the need for precise alignment and temperature control of the laser crystals and etalon.
