Abstract Laser cavities which can generate different types of ultrashort pulses are attractive for practical applications and the study of pulse dynamics. Here, we report the first experimental observation of both conventional solitons (CS) and dissi

The evolution of soliton pulses into noise-like pulses in a nonlinear fiber externally to the laser oscillator is demonstrated at 1.9 µm, for the first time. Soliton collapse based mechanisms induce noise-like pulses with varying properties as a fun

Both conventional solitons (CS) and dissipative solitons (DS) are generated in a $\boldsymbol{2 \mu \mathrm{m}}$ fiber ring laser cavity. By adjusting the intracavity polarization controller positions and modifying the pump power, switching between d

Conference on Lasers and Electro-Optics.
We demonstrate that soliton pulses centered at 1.9 μm can evolve into noise-like pulses in a high numerical aperture fiber. The amplified pulses have an energy of 56 nJ and a duration of 210 fs after compression.

We demonstrate an all-fiber thulium-doped laser system that can generate 105-nJ pulses with a repetition rate of 21 MHz at 1890nm. The amplified pulses can be compressed to a pulse duration of 280 fs.

Gaussian beam profile is the most widely used beam type in laser-material processing. However, these beams are practically limited when they are focused, due to their diffraction-limited focal depth. Consequently, in order to fabricate elongated, hig
