Abstract
We report a high resolution spectroscopic characterisation of Nd:KGW as a function of temperature, over the range 80 K - 450 K. Measurements were made for the two dominant polarizations, with respect to the principal optical axes for the double tungstate crystal, namely E//Nm and E//Np for an Ng – cut crystal. Knowledge of the critical spectroscopic characteristics at various temperatures enables more accurate prediction of laser performance over a large range of possible operating conditions.
