Abstract
An active mode-locking pulse laser generator comprising: an active fibre doped with a fluorescent dopant; active-fibre pumping means; a modulator to be driven from the outside, connected in series to said active fibre; a wavelength selecting filter, to be driven from the outside, connected in series to said active fibre; means for drawing an emission signal from said active fibre; means for defining a laser cavity including the active fibre, pumping means, modulator, filter, and signal drawing means, wherein the drivable modulator is adapted to generate a modulation of the emission signal generated by the active fibre, such as to cause a mode-locking of the oscillating emission signal in the cavity, wherein the wavelength selecting filter consists of an optical-waveguide monolithic filter, in the absence of components subjected to spatial-configuration modifications.
