We report, to the best of our knowledge, the first demonstration of a gain-switched fiber laser operating near 3.5 μm. A dual-wavelength pumping scheme consisting of a 1976 nm Q-switched fiber system… (More)
We report on a splice-free erbium-doped all-fiber laser emitting over 20 W at a wavelength of 1610 nm, with a slope efficiency of 19.6 % and an overall efficiency of 18.3% with respect to the… (More)
We report, to the best of our knowledge, the first entirely monolithic dysprosium (Dy)-doped fluoride fiber laser operating in the mid-IR region. The system delivers 10.1 W at 3.24 μm in continuous… (More)
We report a passively mode-locked Dy3+:fluoride fiber laser emitting around 3.1 μm based on the nonlinear polarization evolution technique in a ring configuration, using in-band pumping at 2.8 μm.… (More)
During the 2015 International Year of Light, Universite Laval's SPIE Student Chapter volunteered to create a fully autonomous exhibition explaining the basics of light to the public. Composed of two… (More)
Using fiber Bragg gratings written directly in the gain fiber through the polymer coating, we demonstrate a scalable and extremely simple erbium fiber laser emitting over 20 W of power at 1610 nm.
