本文报道了自1998年发现以来，首次报道了无中心Yb ~（3+）掺杂La_2CaB_（10）O_（19）（Yb：LCB）晶体的激光运转。计算了Yb：LCB的偏振吸收和发射截面谱。采用光纤耦合的976 nm半导体激光器（LD）作为泵浦源，实现了1030和1040 nm左右的双波长激光输出。Y切Yb：LCB晶体的斜率效率最高，为50.1%。此外，通过相位匹配晶体谐振腔的设计，在Yb：LCB晶体中实现了521 nm的自倍频（SFD）绿色激光输出，输出功率为152 mW。这些结果促进Yb：LCB作为一种有竞争力的多功能激光晶体，特别是对于从可见光到近红外范围的高度集成的微芯片激光器件。(c)2022光学出版集团
We report the first, to the best of our knowledge, laser operation of acentric Yb3+-doped La2CaB10O19 (Yb:LCB) crystal since its discovery in 1998. The polarized absorption and emission cross-section spectra of Yb:LCB were calculated at room temperature. Using a fiber-coupled 976nm laser diode (LD) as the pump source, we realized effective dual-wavelength laser generation at around 1030 and 1040 nm. The highest slope efficiency of 50.1% was obtained in the Y-cut Yb:LCB crystal. In addition, via resonant cavity design on a phase-matching crystal, a compact self-frequency-doubling (SFD) green laser at 521nm was also realized in a single Yb:LCB crystal with an output power of 152mW. These results promote Yb:LCB as a competitive multifunctional laser crystal, especially for highly integrated microchip laser devices ranging from the visible to the near-infrared regime.
