Abstract
An efficient dual-wavelength laser-diode-pumped Nd:YAG ceramic laser operating at 1112 and 1116nm is demonstrated. We obtain a maximum total output power of 3.43 W including a 1.77W 1112nm component and a 1.66W 1116nm component under a pump power of 16.1 W, corresponding to a slope efficiency of 23.7% and a total optical-to-optical efficiency of 21.3%.
