【Abstract】 Using the transmission characteristic of the Gaussian beam after a lens and the thermal stability in a broad range of the special telescopic resonator, an adaptive compensatory system for thermal lens focus is designed to weaken the effect of the thermal lens in light pumped solid lasers. Thus, a stable output radius can be achieved while the thermal lens focus varies in a broad range.更多还原
