Abstract :
We report on room temperature continuous wave laser generation at ~1062 nm from proton implanted Nd:GGG planar waveguides. Single-mode stable laser operation is realized with an 808-nm pump source, resulting in a laser threshold of ~49.3 mW and slope efficiency of 30%. The maximum output power of ~21.9 mW, an absorbed pump power of ~117.4 mW, leads to an optical-to-optical conversion efficiency of 18.7%.
