用TGT法成功地生长了Yb：CaF_2-SrF_2无序晶体。利用双壁碳纳米管可饱和吸收体（DWCNT-SA），首次研究了Yb：CaF 2-SrF 2晶体在二极管泵浦下的连续锁模激光特性。锁模激光器在中心波长为1045.5 nm处提供短至5 ps的脉冲，无需任何色散补偿。该振荡器工作在1087 MHz的重复频率，提供292 mW的平均输出功率。
Yb:CaF2–SrF2 disordered crystals are successfully grown by the TGT method. By using a double-walled carbon nanotube saturable absorber (DWCNT-SA), the continuous-wave mode-locked (CWML) laser properties of Yb:CaF2–SrF2 crystals are demonstrated under diode pumping for the first time. The mode-locked laser delivers pulses as short as 5 ps at a center wavelength of 1045.5 nm without any dispersion compensation. The oscillator operating at a repetition rate of ∼87 MHz delivers 292 mW average output power.
