Paper Abstract

Efficient quasi-three-level emission at 946 nm in Nd:YAG requires a proper balance between the laser emission and the reabsorption induced by the residual thermal population of the terminal laser level. The paper shows that the emission properties can be increased by direct 885 nm pumping into the emitting level (slope efficiency in absorbed power equal to 0.68, compared with 0.48 for the traditional pumping at 809 nm) and infers that the reduced pump absorption can be overcome by using laser resonators with multi-pass of pump radiation inside the laser material.
