我们首次演示了单斜化学计量晶体KYb(WO4)2(以下简称KYbW)的激光手术。2f5 /2上的激光?利用0.5 mm厚的KYbW板,在1074 nm附近实现了Yb3+的2f7 /2室温转变,斜率效率为>41%(最大转换效率为>26%)。这种新型激光材料在二极管泵浦高功率激光器、薄圆盘和波导设计以及超短(ps/fs)脉冲激光系统中具有很大的前景。
We demonstrate for the first time laser operation with the monoclinic stoichiometric crystal KYb(WO4)2(hereafter KYbW). Lasing on the2F5/2?2F7/2transition of Yb3+at room temperature has been achieved near 1074 nm with >41% slope efficiency (>26% maximum conversion efficiency) using a 0.5-mm-thick plate of KYbW. This new laser material holds great promise for diode-pumped high-power lasers, thin-disk and waveguide designs as well as for ultrashort (ps/fs) pulse laser systems.
