Mode locking based on an epitaxial composite of the monoclinic double tungstate crystal Yb:KLu(WO4)2 is realized. A 100 microm thin Yb:KLu(WO4)2 layer grown on a KLu(WO4)2 substrate is used as an active medium in a laser passively mode locked by a semiconductor saturable absorber. Pulse durations of 114 fs have been achieved for an average power of 31 mW at 1030 nm. Results in the femtosecond and picosecond regimes of the Yb:KLu(WO4)2/KLu(WO4)2 laser are presented. The great potential of Yb-doped tungstate composite structures as active elements for mode-locked laser systems is demonstrated.
实现了基于单斜双钨酸盐晶体Yb:KLu(WO4)2外延复合材料的锁模。在KLu(WO4)2衬底上生长的100微米厚的Yb:KLu(WO4)2层被用作由半导体可饱和吸收体被动锁模的激光器中的有源介质。在1030nm波长下，平均功率为31mW时，实现了114fs的脉冲持续时间。给出了Yb:KLu(WO4)2/KLu(WO4)2激光器在飞秒和皮秒 regime下的结果。证明了掺镱钨酸盐复合结构作为锁模激光系统有源元件的巨大潜力。
