Laser Diode Pumped Dy∶YAG Yellow Laser
A new miniature diode-end-pumped Dy∶YAG yellow laser based on the domestic single crystal is reported. According to the special energy structure of Dy∶YAG laser crystal, the yellow laser of 582.7 nm on the 4F9/2→6H13/2 transition is obtained using laser diode pump at room temperature. In order to matching the pump wavelength with the Dy∶YAG crystal absorption peak, the blue LD is used as the pumping source, and the center wavelength is optimized at 447.3 nm by tuning the LD operative temperature. With a total incident pump power of 1.4 W, the yellow laser maximum output power of 56 mW is achieved. The maximum single pulse energy is up to 1.1 mJ. The optical-to-optical conversion efficiency is 4% and the slope efficiency is 5%.
