Abstract :
A report is presented of the thermal shifts of eleven of the twelve lines from the /sup 4/F/sub 3/2/ Stark energy levels to the /sup 4/I/sub 11/2/ energy levels in an Nd:YAG laser for a temperature change from 20-200 degrees C. The thermal shift difference between the Stark sublevels R/sub 1/, R/sub 2/ in /sup 4/F/sub 3/2/ is found to be about -0.6+or-0.6 cm/sup -1//100 degrees C. Within experimental uncertainty, all of the lasing lines either moved to longer wavelength or remained unchanged with increasing temperature.<>
