A thulium laser
Abstract
The functional scheme of a thulium medium allowing efficient laser action under wideband lamp pumping is proposed. Pump-energy dependences of lasing energy and gain are presented for GSGG:Cr-Tm (3 percent), lasing at 1.994 micron, and for YAG:Cr-Tm (7 percent), lasing at 2.014 microns. It is shown that the use of crystals with higher Tm concentration leads to a significant increase in efficiency with substantial change in lasing threshold.
