Single-mode linearly polarized high power fiber laser at 1120 nm

Abstract: A 100 W-class all-fiber linearly-polarized single-mode fiber laser at 1120 nm with an optical pump efficiency of 50% was demonstrated. Linearly polarized output with a polarization extinction ratio of 15 dB is achieved by a cavity that selects both wavelength and polarization. Macro pulse operations with square shaped pulses from 100 μs to 1 ms are achieved without relaxation oscillation. The exact wavelength of pump diode is found to be crucial for amplified spontaneous emission and parasitic oscillation in h… Show more

“…[1], and have already found a wide range of applications in optical pumping, frequency conversion, optical communications, fiber sensing, biology, and supercontinuum generation [2][3][4][5][6][7][8]. Up to date, the investigation into RFLs has covered many areas, including power scaling [9,10], linewidth narrowing [11,12], temporal characteristics [13,14], polarization state [15], and working wavelength expansion [16,17], among which the temporal stability is an important aspect that affects the performance of RFLs.…”

“…However, obtaining a high brightness laser from a single fiber is limited by thermal effects, facet damage, and deleterious nonlinearities [2]- [4]. Current beam combinations, including spectral beam combination (SBC) [5] and coherent beam combination (CBC), are potential ways to overcome these limits.…”
