Abstract
A new method of using thermally induced second-harmonic output depolar ization to determine the fractional thermal loading of a diode-pumped Nd:YVO4 laser is proposed. The experimental results show that the frac tion of the green output power polarized along the extraordinary axis of a KTP crystal, f(e), is an oscillatory function of the absorbed pum p power. The fractional thermal loading can be determined by measureme nt of the difference in the absorbed pump power between the peaks of f (e). (C) 1998 Optical Society of America.
