High Power Medical All-Solid-State 561 nm Yellow Laser
The high power output of medical all-solid-state 561 nm yellow laser is achieved by the method of semiconductor-pump intracavity frequency doubling. After the comparison and analysis for laser parameters of the main lines parameters of the NdYAG laser crystal, the high-gain 1064, 1319 and 946 nm line operations suppressed by the membrane system design of the resonator cavity. Through the rational choice of the nonlinear crystal and the reasonable control of crystal placement angle and matched temperature, the single line of 561 nm output is obtained. The output power is 1.41 W at the incident pump power of 13.5 W, with the light to light conversion efficiency of 10.5%.
