In this paper, we reported the realization of 2nd-order random lasing in a half-opened fiber cavity, which is formed by a FBG with central wavelength at the 1st-order Raman Stokes wavelength and a single-mode fiber (SMF) performing as a random distributed feedback mirror. Using this proposed method, the threshold of 1st-order (2nd-order) random lasing is reduced to 0.7 (2.0) W, which is nearly 2 times lower than that observed in a completely-opened cavity.
在本文中，我们报道了在半开放光纤腔中实现二阶随机激光，该腔由中心波长位于一阶拉曼斯托克斯波长的光纤布拉格光栅（FBG）和用作随机分布反馈镜的单模光纤（SMF）构成。采用这种方法，一阶（二阶）随机激光的阈值降低到了0.7（2.0）瓦，比在完全开放腔中观察到的阈值低近两倍。
