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