Abstract

Experimental investigation ofd Nd:YAG monolithic nonplanar ring lasers operated at 1123nm wavelength is presented. Stable single-frequency 1123nm laser output has been obtained with successful suppression of the strong 1064nm radiation. Single-frequency output power of 1.25W is demonstrated with a pump power of 3.98W at 808nm, which gives a slope efficiency of 39%. The laser frequency tuning range is over 3GHz, and the average tuning rate with temperature is 2.6GHz°C. A strong iodine absorption line can be covered within the laser frequency tuning range.
