Single-mode Nd : GGG disk laser with three-beam diode pumping and a degenerate cavity

摘要

The energy and spatial output parameters of a solid-state Nd : GGG disk laser with three-beam pumping and a degenerate cavity with a single output channel are studied. The radiation was coupled out of the cavity through either an auxiliary semitransparent output mirror or a variable-reflectivity mirror. The single off-axis intracavity beam successively propagated through all the pumped regions of the active element.
