报道了掺Yb：NaY（WO4）2（Yb：NaYW）晶体的被动锁模激光运转，平均功率为400 mW。这是我们所知的锁模Yb：NaYW激光器的最高功率。该激光器采用高功率光纤尾纤激光二极管线阵端面泵浦，半导体可饱和吸收镜实现锁模。激光脉冲宽度为1.1ps，中心波长为1019.7nm，带宽为1.6nm，接近变换极限。
Passively cw mode-locked laser operation of Yb-doped NaY(WO4)2 (Yb:NaYW) crystal was demonstrated with an average power of 400 mW. This is the highest power achieved from the mode-locked Yb:NaYW laser to our knowledge. The laser was end-pumped by a high power fiber pigtailed laser diode bar and the mode-locking was enabled by a semiconductor saturable absorber mirror (SESAM). The laser pulse duration was 1.1 ps, centered at the wavelength of 1019.7 nm with a bandwidth of 1.6 nm, and nearly transform-limited.
