Pulses of 118 nJ at the repetition rate of 170 kHz and central wavelength of 2097 nm have been produced by holmium fiber laser Q-switched by carbon nanotube saturable absorber. Efficient operation of holmium fiber with fairly high-doping level has be

We propose an advanced scheme of amplifier similariton laser providing an output pulse spectrum much wider than the gain bandwidth. The proposed scheme demonstrates a drastic increase of the output pulse spectrum width, reduction of the pulse duratio

Saturable absorber based on PbS quantum-dot-doped glasses exhibiting bi-temporal recovery dynamics provides effective means for control of vector soliton bunching in 2-μm spectral range. The slow response of absorption creates an attractive force be

A promising method for the diminishing of loss upon the welding of microstructured optical fibers with suspended core is proposed. The method is based on the application of the nitrogen-doped optical fiber whose thermally expanding core serves as the

We report the interpulse dynamics in fiber soliton laser because of depletion and relaxation of gain and absorption. The soliton interaction range is shown to depend largely on the relaxation time of dissipative parameters while the compensation of t

We demonstrate the method of stable bound solitons formation by applying the active loss modulation into the cavity. The modulation at high harmonic of cavity frequency could efficiently prevent irregular soliton bunching and result in the developmen

Effect of the gain medium dispersion on stability of soliton groups in fiber laser has been studied. An attractive force produced by bi-temporal saturable absorber is used to enhance the soliton interaction and results in a firm bound state formation
