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…
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…
Sub-surface modifications in silicon with ultrashort pulsed lasers above 2 microns
Roland A. Richter, Nikolai Tolstik, Sebastien Rigaud +7
Nonlinear optical phenomena in silicon such as self-focusing and multi-photon absorption are strongly dependent on the wavelength, energy and duration of the exciting pulse. Thus,…
