【Abstract】 A laser interferometry method of measuring the thermal lensing of end_pumped solid_state lasers is proposed. This method provides a way easy to be carried out is real_time, having no influence on laser system, with a high spatial resolution for diagnosing thermal lensing. By this method, thermal lensing of end_pumped Nd:YVO 4 laser is studied in detail. And this work provide a means for studying the thermal effects of laser medium and designing lasers of this kind.更多还原
