A comparative study of thermal lensing effect in diode laser pumped N-g- and N-p-cut Nd:KGd(WO4)(2) (KGW) laser crystals was performed for laser emission polarized along the principle refractive axis, N-m. The thermal lens in the N-g-cut Nd: KGW was found to be weakly astigmatic with a positive refractive power for both the N-m- and N-p-directions. For N-p -cut Nd: KGW, strong astigmatism was observed and the refractive powers in the N-g- and N-m-directions had opposing signs. The degree of astigmatism was found to be considerably weaker for the N-g-cut Nd: KGW in comparison with the N-p-cut one: 0.35 dptr/(W/cm(2)) and 2.85 dptr/(W/cm(2)), respectively. The ratio of the thermal lens refractive powers in the planes parallel and perpendicular to the laser emission polarisation were measured as + 1.4 and -0.425 for N-g- and N-p-cut Nd: KGW respectively.
