The mode locking of the mixed sesquioxide single crystal Yb:LuScO(3) is demonstrated. This crystal is locally disordered and has the broadest emission spectrum of all sesquioxides known so far. Pulse durations as short as 111 and 74 fs were obtained using the semiconductor saturable absorber mirror and Kerr-lens mode locking, respectively. The latter regime was reached using a two-section distributed Bragg-reflector tapered diode laser as a pump source.
混合 sesquioxide 单晶体 Yb:LuScO(3) 的锁模特性得到了证明。这种晶体存在局域无序,并且具有迄今为止所有 sesquioxide 中最宽的发射光谱。使用半导体可饱和吸收镜和克尔透镜锁模,分别获得了最短为 111fs 和 74fs 的脉冲持续时间。后一种锁模状态是使用两段分布式布拉格反射锥形二极管激光器作为泵浦源实现的。
