| Abstract: | By aiming the pump wavelength of the laser diode to the absorption peak at 811 nm of the (Nd 0.005 Lu 0.4975 Y 0.4975 ) 2 SiO 5 (Nd:LYSO) crystal, an efficient dual-wavelength operation at 1 075 and 1 079 nm is obtained. The maximum output power is 702 mW when the incident pump power is 2.53 W, corresponding to an optical conversion efficiency of 27.7% and a slope efficiency of 37.0% |
