Abstract

Room temperature CW laser performance of 1% and 1.1% Nd:YAG with low power laser diode end-pumping has been studied. The results from Nd:YAG have been compared with the Nd:YLF at similar experimental conditions. The slope efficiency at 1064 nm was determined to be 14.7% for 1% Nd:YAG and 17.4% For 1.1% Nd:YAG laser crystal. For 1% Nd:YLF polarized laser at 1047 nm the efficiency was 6.2%. Laser output power dependencies on the pump power and the pump wavelengths of these diode-pumped solid state lasers were investigated
