NettetWe proposed a short-linear-cavity (SLC) fiber laser based on a virtual-folded-ring (VFR) resonator and a fiber Bragg grating Fabry–Perot filter. Spatial hole burning effect was reduced by retarding the polarization state of the counter-propagating light waves utilizing the VFR structure. The photon lifetime of the resonator was extended due to the multi … Nettet2. mar. 2024 · However, it is challenging to design environmentally stable NPE fiber oscillators using only polarization-maintaining (PM) fibers.
