We experimentally characterized the laser-induced thermal effect on fused silica and established a method to remove the thermal load using passive optics. Based on the formula analyzed in [J. Kor. Phys. Soc. 69. 1531 (2016)], we were able to determine the specific length of the compensating material to remove the thermal effect. Remarkably, the thermal compensation was observed when the compensating material was placed before or after the material subject to thermal lensing. Our results demonstrate that one single passive optic can be used to overcome the thermal effect for various laser powers without any additional optics.
