Toward a Thermodynamic Framework for Dissipative Solitons: From Photonics to Turbulence and Bose--Einstein Condensate Analogies

Vladimir L. Kalashnikov, Irina T. Sorokina

# Abstract Thermodynamic concepts are increasingly used in nonlinear photonics to describe Rayleigh--Jeans thermalization, optical wave turbulence, condensation, negative-temperatu…

Driven Dissipative Soliton Resonance

Vladimir L. Kalashnikov, Alexander Rudenkov, Evgeni Sorokin +1

We investigate the enhancement of the dissipative soliton energy scalability by the injection of a low-power single-mode seed synchronized with a chirped-pulse oscillator round-tri…

Energy Scalability Limits of Dissipative Solitons

Vladimir L. Kalashnikov, Alexander Rudenkov, Evgeni Sorokin +1

In this study, we apply a thermodynamical approach to elucidate the primary constraints on the energy scaling of dissipative solitons (DS). We rely on the adiabatic theory of stron…

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…
