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…
Thermodynamics of Dissipative Solitons
Vladimir L. Kalashnikov, Alexander Rudenkov, Irina T. Sorokina
We establish a close analogy between the thermodynamics of the nonlinear systems far from equilibrium and the dissipative solitons. Unlike the solitons in the Hamiltonian systems,…
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…
At the threshold of distributed Kerr-lens mode-locking in a Cr:ZnS waveguide laser
Maksim Demesh, Vladimir Kalashnikov, Evgeni Sorokin +3
We demonstrate feasibility of spatiotemporal mode-locking in a mid-IR Cr:ZnS waveguide laser based on the nonlinear spatial mode coupling. The experiment shows efficient power scal…
Atmospheric dispersion management in the mid-IR mode-locked oscillators
Evgeni Sorokin, Alexander Rudenkov, Vladimir Kalashnikov +1
The atmospheric dispersion in the mid-infrared transparency windows presents and important albeit frequently neglected factor when developing ultra-short pulsed lasers. We show tha…
