Chirped pulse waveguide amplifier
Alexander Rudenkov, Vladimir L. Kalashnikov, Maxim Demesh +3
We introduce a single-mode Cr:ZnS crystalline waveguide ultrafast amplifier that provides a high gain of 5.5 dB/cm and 2.35 W of average output power. The depressed-cladding buried…

Dissipative spatiotemporal soliton in a driven waveguide laser
Vladimir L. Kalashnikov, Evgeni Sorokin, Irina T. Sorokina
A distributed Kerr-lens mode locking regime can be realized in a waveguide laser by spatial profiling of the pump beam, thus creating a spatio-temporal soliton. Additional slow tem…

Dissipative Soliton Resonance: Adiabatic Theory and Thermodynamics
Vladimir L. Kalashnikov, Alexander Rudenkov, Evgeni Sorokin +1
We present the adiabatic theory of dissipative solitons (DS) of complex cubic-quintic nonlinear Ginzburg-Landau equation (CQGLE). Solutions in the closed analytical form in the spe…
