“…So far, two formation mechanisms were mainly proposed to form square pulse in fiber lasers. As one of the formation mechanisms, the peak power clamping effect of the laser cavity was used to obtain square pulse [10], [11]. Very recently, N. Akhmediev et al theoretically proposed another new soliton formation mechanism, namely dissipative soliton resonance (DSR) [12]- [14], to generate the square pulse in fiber lasers.…”

The generation of multiwavelength square pulses is demonstrated in a passively mode-locked figure-eight fiber laser. The multiwavelength square pulses were found to be structured by superposing the square pulses centered at different wavelengths, whose pulse duration broadens with the increasing pump power. The square pulse was confirmed as the noise-like pulse by using an autocorrelator. By properly rotating the PCs, the dual-or triple-wavelength square pulse could be achieved. The obtained results provide a new viewpoint for understanding the formation mechanism of the multiwavelength pulses with noise-like square profiles in fiber lasers.Index Terms-Mode-locked fiber lasers, multiwavelength, square pulse, noise-like pulse.

“…Novel features such as the transform-limited soliton-pulse formation, 1,2 pulse-energy quantization, 2,3 harmonic mode locking, 4,5 and noiselike-pulse output 6,7 have been observed in the laser. In this paper we report on another intrinsic behavior of the laser; we show experimentally that by simple adjustment of the polarization controllers of the laser, the central wavelength of the mode-locked pulses can be continuously tuned.…”

“…The self-started mode locking of the laser is achieved by use of the nonlinear polarization-rotation technique. 2,[12][13][14] To this end two polarization controllers, one consisting of two quarter-wave plates and the other consisting of two quarter-wave plates and one half-wave plate are used to control the polarization of the light. The wave plates and the polarization-dependent isolator are mounted inside a fiber bench, which is a fiber-to-fiber coupling system used for coupling light from one fiber to another across a 7-cm open-air gap.…”

We have experimentally observed continuous-wavelength tuning in a passively mode-locked fiber ring laser. Depending on the polarization setting, two separated tuning ranges are observed. We show that the wavelength tuning is a result of the existence of birefringence in the laser cavity. We have also shown that the same mechanism is responsible for the power asymmetry of sidebands appearing in the soliton spectrum.

“…The high linear absorption coefficient, modulation depth and damage threshold of InN allow the generation of high-power pulses while keeping the CW laser emission blocked. The polarization independence is an advantage over those mode-locked fiber lasers whose principle of operation is based on a nonlinear-rotationpolarization acting as the saturable absorber, which need periodical readjustment of the polarization [39][40][41]. The study of the laser output properties for high pulse energy conditions is performed by inserting additional single-mode fiber between the output coupler and the variable attenuator (see Fig.…”

(Article begins on next page) Abstract:The growing demand of ultrafast mode-locked fiber lasers in the near infrared has boosted the research activity in this area. One of the most convenient ways to achieve passive mode locking consists of inserting a semiconductor saturable absorber in the laser cavity to modulate the losses. However, in such a configuration, the limited power range of operation is still an unsolved issue. Here we report the fabrication of an ultrafast, high-power, widely powertunable and non-polarization-dependent mode-locked fiber laser operating at 1.55 µm, using an InN layer as saturable absorber. With post-amplification, this laser delivers 55-fs pulses with a repetition rate of 4.84 MHz and peak power in the range of 1 MW in an all-fiber arrangement.
