摘要
We demonstrate,for the first time and to the best of our knowledge,a continuous-wave and broadly tunable Cr:ZnSe bulk crystal laser pumped by a Tm:YLF bulk laser with 1845 nm and 1887 nm wavelengths.We compare the output characteristics and wavelength-tuning properties of the continuous-wave operation at the two pump wavelengths.In the continuous-wave operation,the maximum output power is 1.79 W with a slope efficiency of 28.8%,which is achieved at the pump wavelength of 1887 nm.In addition,a tuning range of~700 nm(696 nm)from 2040 nm to 2736 nm by using a reflective diffraction grating is realized.To the best of our knowledge,this is the widest tuning range realized so far for Cr:ZnSe bulk crystal tuned by gratings.
