| Abstract: | A report is presented of the thermal shifts of eleven of the twelve lines from the 4F3/2 Stark energy levels to the 4I11/2 energy levels in an Nd:YAG laser for a temperature change from 20-200°C. The thermal shift difference between the Stark sublevels R1, R2 in 4F3/2 is found to be about -0.6±0.6 cm-1/100°C. Within experimental uncertainty, all of the lasing lines either moved to longer wavelength or remained unchanged with increasing temperature |
