Abstract

We measured the thermo-optic coefficients d n / d T of anisotropic Nd : KGd ( WO 4 ) 2 crystals at the wavelengths of 1.064 μm and 532 nm ( 300 K ) by a beam deflection method. The values of d n / d T are determined to be d n p / d T = 16.0 × 10 6 K 1 , d n m / d T = 11.8 × 10 6 K 1 , and d n g / d T = 19.5 × 10 6 K 1 (at 1.064 μm ) and d n p / d T = 14.3 × 10 6 K 1 , d n m / d T = 10.0 × 10 6 K 1 , and d n g / d T = 15.0 × 10 6 K 1 (at 532 nm ). Thermal lensing in the flashlamp-pumped N p - and N g -cut Nd : KGd ( WO 4 ) 2 laser rods was studied at 1.064 μm by a probe beam technique in the nonlasing conditions, and the contribution of the photoelastic term to the thermal lens optical power was estimated. Athermal propagation directions with the definitions d n / d T + ( n 1 ) α T = 0 and d n / d T + n α T = 0 were found in Nd : KGd ( WO 4 ) 2 .
