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…
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…
Femtosecond laser writing of the depressed cladding buried channel waveguides in ZnS crystal
E. Sorokin, A. Okhrimchuk, N. Tolstik +4
We report the first direct femtosecond laser-writing of buried channel waveguides in monocrystalline ZnS. We also report the first single-mode Cr:ZnS depressed cladding buried wave…
A route to high peak power and energy scaling in the mid-IR chirped-pulse oscillator-amplifier laser systems
Alexander Rudenkov, Vladimir L. Kalashnikov, Evgeni Sorokin +2
The paper introduces a new route towards the ultrafast high laser peak power and energy scaling in a hybrid mid-IR chirped pulse oscillator-amplifier (CPO-CPA) system, without sacr…
