Methodical inaccuracy of the Z-scan method for few-cycle terahertz pulses
Scientific Reports, 2019 Modern sources of THz radiation generate high-intensity pulses allowing to observe nonlinear effects in this spectral range. To describe many nonlinear effects theoretically, it is necessary to know the nonlinear refractive index coefficient of optical ...

Stable Gain-Guided Soliton Propagation in a Polarized Yb-Doped Mode-Locked Fiber Laser
IEEE Photonics Journal, 2012 We demonstrate gain-guided dissipative soliton operation of a linearly polarized Yb-doped fiber laser, mode-locked by carbon nanotubes. In the regime of low nonlinear phase shift per cavity roundtrip, a dissipative soliton pulse can be supported by the ...
