Laser performance of a glass‐clad LiNdP4O12 rectangular waveguide

摘要

A LiNdP4O12 rectangular waveguide clad by sputtered SK5 glass was fabricated. Quasi‐cw laser operations at 1.048 and 1.317 μm were obtained both in an Ey00 single‐transverse mode, by argon‐laser coaxial pumping (0.5145 μm). The round‐trip cavity losses were evaluated to be 14.3% (1.05 μm) and 6.5% (1.32 μm). Waveguide‐mode calculation, observed laser‐characteristics analysis, and transverse‐pumping estimation are also described.
