Q2: Consider the lamp-pumped Nd:YAG laser (n=1.82). The pumping beam induces a thermal lens of focal length (f) the rod is simulated by a thin lens of focal length (f-25cm) placed at the resonator center. Calculate: - The mirror separation so that the resonator is equivalent to confocal resonator. - The optical length of the resonator due to effect of thermal lensing. - The TEM00 mode spot size at the lens position.
