    • 1.9 micron Tm3+-doped germanate fiber laser source for Si-processing 

      Dvoyrin, Vladislav; Sorokina, Irina T; Okhotnikov, Oleg; Mashinsky, Valery M.; Ischakova, Lyudmila D.; Dianov, Evgenii M; Khopin, Vladimir F.; Guryanov, Aleksey N. (Chapter, 2011)
      We report development of a novel Tm3+ -doped fiber laser source at 1.86 μm based on highly nonlinear 55GeO2-45SiO2 dispersion shifted fiber, applicable to 3D-volume microprocessing of Si.

    • Femtosecond Cr:ZnS laser at 2.35 µm mode-locked by carbon nanotubes 

      Tolstik, Nikolai; Okhotnikov, Oleg; Sorokin, Evgeni; Sorokina, Irina T (Journal article; Peer reviewed, 2014)
      We report the solid-state Cr:ZnS laser mode-locked by CNT-based saturable absorber. The absorber was deposited on a protected silver mirror used as a high reflector mirror in a standard 250-MHz cavity with chirped mirror ...
