报道了一台低温（77K）下高功率激光二极管泵浦Yb：CaF（2）激光器。当泵浦功率为245 W时，获得了97 W的1034 nm激光输出。相应的全局提取效率（相对于吸收的泵浦功率）为65%。激光器小信号增益被发现等于3.1。激光波长可以在990和1052 nm之间调谐，峰值与低温下记录的增益截面谱的结构很好地对应。
We present a high-power diode-pumped Yb:CaF(2) laser operating at cryogenic temperature (77 K). A laser output power of 97 W at 1034 nm was extracted for a pump power of 245 W. The corresponding global extraction efficiency (versus absorbed pump power) is 65%. The laser small signal gain was found to be equal to 3.1. The laser wavelength could be tuned between 990 and 1052 nm with peaks that correspond well to the structure of the gain cross-section spectra registered at low temperature.
