Simultaneous Generation of Two Types of Pulse Shape in an Yb-Doped Fiber Laser System

Bound noise-like pulse generation from Yb-doped passively mode-locked fiber lasers

“…Passively mode-locked fiber lasers have attracted much interest since they were invented because they have many potential applications, such as material processing [1], optical communications [2], medicine [3] and sensing [4]. Due to the high nonlinearity inside the cavity, mode-locked fiber lasers also provide a platform for exploring some special pulse dynamic processes, such as soliton molecules [5], dissipative soliton resonance [6], dark solitons [7], and noise-like pulses (NLP).…”

Raman Gain Square‐Wave Noise‐Like Pulse Laser Pumped by a Random Fiber Laser

“…Square-wave noise-like pulse (NLP), composed of many substochastic short pulses, has potential applications in micromachining, supercontinuum generation, and optical coherence tomography, due to characteristics of low coherence and high energy. [1][2][3] In recent years, square-wave NLP has been generated both in normal and anomalous regimes, [4][5][6][7][8][9] using traditional mode locking techniques, such as nonlinear polarization rotation (NPR), [4,5] nonlinear optical loop mirror, [6] nonlinear amplifying loop mirror, [5,7,8] as well as novel methods, such as 2D materials due to the rapid development of this new field. [9][10][11] Most of these works used rare earth doped fibers to provide optical gain limited in particular wavelength range, while Raman fiber lasers can exactly make up for this weakness.…”
