报道了在Yb3O4：Sr3Y（BO3）3晶体中首次实现激光作用的实验结果.这种新材料具有特别宽的吸收和发射带宽（分别为6和60 nm），因此对于二极管泵浦飞秒和可调谐激光源特别感兴趣。报道了从二极管泵浦（用3.6W的二极管泵浦功率获得1.4W的连续激光功率，并且从高功率准连续泵浦获得高达3.4W的峰值功率）连同平滑可调谐性（超过50nm的半高宽）的有效操作。为了比较，在相同的条件下研究了Yb：Glass和Yb：Ca4GdO（BO3）3的效率和热极限。
The first demonstration of laser action in a Yb 3ϩ :Sr 3 Y(BO 3) 3 crystal is reported. This new material exhibits particularly broad absorption and emission bandwidths (6 and 60 nm, respectively) and hence is of particular interest for diode-pumped femtosecond and tunable laser sources. Efficient operation from diode pumping (1.4 W of cw laser power obtained with 3.6 W of diode pump power and as much as 3.4 W of peak power from high-power quasi-cw pumping) together with smooth tunability (over 50 nm FWHM) is reported. For the comparison , efficiency and thermal limitations of Yb:glass and Yb:Ca 4 GdO(BO 3) 3 have been investigated under the same conditions.
