Multibound Soliton Formation in an Erbium-Doped Ring Laser With a Highly Nonlinear Resonator

Abstract

We have studied the generation of low-noise ultrashort multibound solitons in the telecommunication spectral window in an erbium-doped all-fiber ring laser with a highlynonlinear resonator mode-locked by a nonlinear polarization evolution effect. The multibound soliton generation is obtained with more than 20 bound dechirped pulses with a duration of ~ 240 fs at a repetition rate of ~ 11.3 MHz (with a signal-to-noise ratio of ~ 73.3 dB), the relative intensity noise is <-140 dBc/Hz, and the Allan deviation of the repetition frequency does not exceed ~1.3•10-8 with a time averaging window of ~ 100 s.

Multi-Pulse Bound Soliton Fiber Laser Based on MoTe2 Saturable Absorber

“…In theory, the combination of layered materials and fiber taper will greatly enhance the effective third-order nonlinearity in the cavity [ 60 ]. Thus, it can be predicted that bound solitons with five or more pulse would be obtained by further optimizing the MoTe 2 -deposited fiber taper and laser parameters, such as polarization state, pump strength and cavity dispersion [ 61 , 62 , 63 ]. In addition, the cw in the laser may be related to the insufficient modulation depth of the SA.…”

Analysis of the Passive Stabilization Methods of Optical Frequency Comb in Ultrashort-Pulse Erbium-Doped Fiber Lasers

“…It is necessary to note such a generation mode as the multibound solitons (MBSs) [101][102][103]. MBS generation regime [104], soliton molecules [105], and soliton crystals [106] involve a bound state of multiple optical pulses that propagate with a fixed temporal separation through optical fibers.…”

Generation of similariton-like pulse bunch in erbium-doped fiber laser with hybrid mode-locking

“…Recent progress in the field of studying the chaotic dynamics of ultrashort pulse formation has revived interest in ultrashort pulse (USP) fiber lasers, and at the moment they are considered not only as sources of ultrashort pulses, but also as a platform for expanding future applications. Currently, special attention is paid to the study of various multipulse regimes of USP generation, such as multibound solitons 1 , noise-like pulses 2,3 , soliton rain 3 , soliton explosion 4 , rogue waves 5 , and also pulse bunches 6 .…”
