Abstract

A comparative study of thermal lensing effect in diode laser pumped Ng- and Np-cut Nd:KGd(WO4)2 (KGW) laser crystals was performed for laser emission polarized along the principle refractive axis, Nm. The thermal lens in the Ng-cut Nd: KGW was found to be weakly astigmatic with a positive refractive power for both the Nm- and Np-directions. For Np -cut Nd:KGW, strong astigmatism was observed and the refractive powers in the Ng- and Nm-directions had opposing signs. The degree of astigmatism was found to be considerably weaker for the Ng-cut Nd:KGW in comparison with the Np-cut one: 0.35 dptr/(W/cm2) and 2.85 dptr/(W/cm2), 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 Ng- and Np-cut Nd:KGW respectively.

Dependence of the output beam mode diameter as a function of the distance from the output coupler at different pump intensities (Pp/πwp 2) for the Ng - and Np -cut Nd:KGW lasers (cavity length is 26 mm for the Ng -cut Nd:KGW laser and 49 mm for the Np-cut Nd:KGW one). Symbols – experimental data. Lines – results of calculations according to the ABCD-method.

The dependence of thermal lensing on pump intensity (Pp/πwp 2 ) in diode laser pumped (a) Ng -cut -and (b) Np -cut Nd:KGW lasers. Symbols – experimental data on thermal lens refractive power. Solid lines –linear fit to the data.

(a) Measured output power as a function of the pump intensity (Pp/πwp 2) for Np - (squares) and Ng- (circles) cut Nd:KGW lasers for a resonator length of L = 49 mm and with L = 26 mm respectively. Solid and dashed vertical lines indicate the critical pump intensity (Pp/πwp 2)c , above which the output power drops, for Np- and Ng-cut Nd:KGW, respectively. The laser resonators progress along the horizontal lines through the equivalent stability diagram (b) as the absolute value of the refractive power |D| of the thermal lens in the active element increases. (D c)1 and (D c)2 are then the characteristic refractive powers at which the resonators intersects the stability limits.

Table 1 Comparison of the thermal lensing sensitivity factors M and thermal lens’ degree of astigmatism for the Np -cut and Ng -cut Nd:KGW crystals. The factor M is deduced with two different methods, namely: (i) analysis of the laser output beam size in dependence on the distance from the output coupler at different pump intensity; and (ii) analysis of the laser output power as a function of the pump intensity.
