Efficient and stable mode-locking operation at 1075 nm is demonstrated in a double-clad ytterbium-doped fiber laser (DC-YDFL) with WS₂-ZnO deposited on a fiber taper as a saturable absorber (SA). The WS₂-ZnO composite is prepared by a simple and cost-effective heating method and deposited onto the fiber taper before being incorporated into the laser cavity. A high power mode-locked normal dispersion output at 1075 nm with a 3 dB bandwidth, repetition rate, pulse width and pulse energy of 3.7 nm, 10.98 MHz, 459 fs and 139.3 nJ respectively are obtained at a pump power of 3.65 W. Due to the interaction of the WS₂-ZnO nanoparticles with the evanescent field of the propagating signal instead of directly, the SA has a higher laser damage threshold, therefore allowing for higher pulse powers to be obtained.

在双层掺光纤激光器（DC-YDFL）中，WS ₂ -ZnO作为可饱和吸收剂（SA）沉积在纤维锥上，证明了在1075 nm处有效且稳定的锁模操作。WS ₂ -ZnO复合材料是通过简单且经济高效的加热方法制备的，并在掺入激光腔之前先沉积在纤维锥上。在3.65 W的泵浦功率下，分别获得了1075 nm的高功率锁模法向色散输出，其3 dB带宽，重复率，脉冲宽度和脉冲能量分别为3.7 nm，10.98 MHz，459 fs和139.3 nJ。 WS ₂的交互-ZnO纳米粒子具有传播信号的e逝场而不是直接传播的信号，SA具有较高的激光损伤阈值，因此可以获取较高的脉冲功率。
