Gain switched fiber laser
WebThis document presents the development of the first gain-switched fiber laser emitting around 3.5 μm. This laser is based on the dual-wavelength pumping of an erbium-doped fluorozirconate fiber by a continuous 976 nm laser diode and a 1976 nm pulsed system based on a thulium doped silica fiber that was developped for this purpose. WebMay 20, 2013 · Abstract Gain-switching of a CW fiber laser is a simple and cost-effective approach to generate pulses using an all-fiber system. We report on the construction of a narrow bandwidth (below 0.1 nm) gain-switched fiber laser and optimize the pulse energy and pulse duration under this constraint.
