Full C-band wavelength-tunable, 250 MHz repetition rate mode-locked polarization-maintaining fiber laser [PDF]

open access: yesScientific Reports, 2023
We demonstrate a full C-band wavelength-tunable mode-locked fiber laser with a repetition rate of 250 MHz, representing the highest repetition rate for C-band tunable mode-locked lasers thus far to the best of our knowledge.

Retiming dynamics of harmonically mode-locked laser solitons in a self-driven optomechanical lattice [PDF]

open access: yesLight: Science & Applications
Harmonic mode-locking, realized actively or passively, is an effective technique for increasing the repetition rate of ultrafast lasers. It is critically important to understand how a harmonically mode-locked pulse train responds to external ...

Multistability manipulation by reinforcement learning algorithm inside mode-locked fiber laser [PDF]

open access: yesNanophotonics
Fiber mode-locked lasers are nonlinear optical systems that provide ultrashort pulses at high repetition rates. However, adjusting the cavity parameters is often a challenging task due to the intrinsic multistability of a laser system.

Dynamics Simulation and Experimental Investigation of Q-Switching in a Self-Mode-Locked Semiconductor Disk Laser

open access: yesIEEE Photonics Journal, 2022
Q-switching in a mode-locked laser not only makes the amplitude of every single output pulse unequal, but also limits the time width and peak power of output pulses.

Low Threshold, High Efficiency Passively Mode-Locked Picosecond Tm,Ho:LiLuF4 Laser

open access: yesFrontiers in Physics, 2020
We experimentally demonstrated a passively mode-locked picosecond Tm,Ho:LiLuF4 laser with low threshold and high efficiency. The stable continuous-wave (CW) mode-locked operation with 12 ps pulse width is obtained by using a five-mirror cavity structure ...
