title = "Amplifier similariton fiber laser with a hybrid-mode-locking technique",
abstract = "By employing both frequency shifting and nonlinear polarization rotation mechanisms in a Yb-doped fiber laser, similariton operation regime is demonstrated. Directly generated pulses from an oscillator has a duration of 7.8 ps with 20.5 nm spectrum width and average output power of 7.4 mW with a repetition rate of 26.4 MHz. The pulses can be externally dechirped to be 140 fs. Through numerical simulations we illustrate the details of similariton pulse formation under the simultaneous action of two mode-locking techniques and advantages of hybrid mode-locking approach.",

note = "Funding Information: To further support stable self-similar evolution in the cavity, we propose to use a hybrid approach incorporating NPR and frequency shifting. NPR results in establishment of pulse operation whereas a small frequency shift of 69.46 MHz leads to efficient filtering of low-intensity CW signal and vanishing undesirable perturbations in the cavity. This technique enables to achieve a stable similariton pulse even with non-optimum NPR parameters. We demonstrate a Yb-doped mode-locked fiber laser generating 7.8 ps similariton pulses with 20.5 nm spectrum bandwidth. The pulses are further compressed down to 140 fs using a grating pair. The experimental work is supported by numerical modelling yielding the insight of hybrid mode-locking operation in the amplifier similariton fiber laser.
