Switchable Dual-Wavelength and Passively Mode-Locked All-Normal-Dispersion Yb-Doped Fiber Lasers

Wavelength and bandwidth tunable passively mode-locked fiber laser based on semiconductor saturable absorber mirror and liquid crystal on silicon device

“…Compared to conventional mode-locked lasers, a tunable-mode-locked laser with flexibly adjustable mode-locked laser parameters, such as output wavelength, pulse repetition frequency, and pulse width, obviously has a wider application potential [4][5][6][7][8]. Graphene and other two-dimensional (2D) noncarbon materials, including topological insulators (TIs), transition metal dichalcogenides (TMDCs), phosphorene, bismuthene, and antimonene, have witnessed a very fast development of both fundamental and practical aspects in mode-locked fiber lasers [9].Several approaches have been proposed to achieve tunable wavelength mode-locked operation, based on a nonlinear optical loop mirror (NOLM) [10] or on polarization-maintaining fiber (PMF) [11].…”

Generation of Multi-pulse Dissipative Solitons in a Mode-Locked Yb-Doped Fiber laser

“…In 2007, A. Chong et al reported a mode-locked all-normal-dispersion giant chirped passively fiber laser system [11], in which the energy of the DSs is above 20nJ. Various ANDi systems such as switchable dual-wavelength laser system [12], tunable high energy giant chirped passively mode-locked fiber laser [13] have also been reported in recently years. In an ANDi system, multi pulses have been observed in the cavity when the pump power is increased to a certain level.…”

Single-polarization, dual-wavelength mode-locked Yb-doped fiber laser by a 45°-tilted fiber grating

“…However, these multi-wavelength YDF lasers emit continuous wave (CW). Up to now, the researches for multi-wavelength pulsed YDF lasers are relatively rare [19][20][21]. Pan et al have realized a passively Q-switched dual-wavelength Yb fiber laser using a Cr4+:YAG saturable absorber [19].…”
