“…However, the effect is rather small and did not deteriorate the laser operation. It is even possible that coupling the spatially dispersed beam into the fiber acts as a spectral filter that helps the mode-locked operation of the laser [24]. The zeroth-order reflection from the grating is used as the output beam instead of the beam from the NPE rejection port to obtain pulses with better quality [23,25].…”

An ultrafast, passively mode-locked fiber laser oscillator has been realized using thulium-doped ZBLAN fibers. Very low dispersion of ZBLAN glass fibers enabled generation of pulses with broad spectra extending from 1730 nm to 2050 nm. Pulses are obtained with the average power of 13 mW at the repetition rate of 67.5 MHz when the pump power is 140 mW. The output pulses are compressed with a pair of SF10 prisms and their durations are measured with SHG FROG, from which we obtained the pulse duration as short as 45 fs.

“…Note, that 1480 nm-pump is likely to give some additional benefits in comparison with 980 nm-pump. For instance, the energy of pulses generated with 980 nm-pump is three times lower [17] than that obtained in a similar scheme with 1480 nm-pump (3.5 nJ against 10 nJ) [18].…”

Abstract-The all-fiber highly-chirped dissipative soliton (HCDS) oscillator was realised at 1.5 μm wavelength. A normal net cavity dispersion was achieved by using a conventional dispersion compensating fiber (DCF). To separate effects of the amplitude self-modulation and dissipative soliton formation, we exploit in the laser cavity both standard single mode fiber and polarization maintaining single mode fiber. The properties of the generated pulses have been varied by changing spectral filter bandwidth and DCF lengths. After compression of the nJ-level ∼6 ps HCDS in the external fiber compressor, we measured the output pulse duration of 165 fs (an estimated chirp parameter 40).

“…As the amplifier similariton evolution produced linearly-chirped pulses with large bandwidth, ~60 fs pulses could be obtained by external compression with a grating pair. By using the same cavity design with Er-doped, dispersion-shifted fiber, pulses with 3.5 nJ pulse energies and ~70 fs pulse duration were achieved [43]. …”

Ultrafast fiber lasers based on self-similar pulse evolution: a review of current progress

Self-similar fiber oscillators are a relatively new class of mode-locked lasers. In these lasers, the self-similar evolution of a chirped parabolic pulse in normally-dispersive passive, active, or dispersion-decreasing fiber (DDF) is critical. In active (gain) fiber and DDF, the novel role of local nonlinear attraction makes the oscillators fundamentally different from any mode-locked lasers considered previously. In order to reconcile the spectral and temporal expansion of a pulse in the self-similar segment with the self-consistency required by a laser cavity's periodic boundary condition, several techniques have been applied. The result is a diverse range of fiber oscillators which demonstrate the exciting new design possibilities based on the self-similar model. Here, we review recent progress on self-similar oscillators both in passive and active fiber, and extensions of self-similar evolution for surpassing the limits of rare-earth gain media. We discuss some key remaining research questions and important future directions. Self-similar oscillators are capable of exceptional performance among ultrashort pulsed fiber lasers, and may be of key interest in the development of future ultrashort pulsed fiber lasers for medical imaging applications, as well as for low-noise fiber-based frequency combs. Their uniqueness among mode-locked lasers motivates study into their properties and behaviors and raises questions about how to understand mode-locked lasers more generally.
