摘要
Abstract
The Tm3+ gain medium with high doping concentration can improve the quantum efficiency of the laser through the cross relaxation process,but it also increases the energy loss caused by energy up-conversion and limits the improvement of laser efficiency.The fluorescence characteristics and laser performance of Tm:SrF2 crystal are studied.Under laser-diode(LD)end-pumping,a continuous-wave laser with a maximum output power of 2.99 W and a slope efficiency of up to 82.1%is realized.The pump threshold of the laser is 0.81 W,and the center wavelength is 1851 nm.Electro-optic Q-switching of the Tm:SrF2 laser is demonstrated.At the repetition rate of 500 Hz,a maximum pulse energy of 1.02 mJ and a minimum pulse width of 45 ns are achieved,resulting in a peak power of 22.67 kW.The experimental results indicate that the Tm:SrF2 laser based on LD pumping has very high efficiency and is expected to be an ideal pump source for optical parametric oscillators(OPOs)and optical parametric amplifiers(OPAs).关键词
