Abstract: A system and method generate laser pulses. Using the modulation signal from a pulse generation module, a seed laser diode generates seed light pulses in response to direct drive current modulation. The seed light pulses have a pulse duration longer than a target pulse duration and a spectral chirp. A compression module has dispersion characteristics over a broad spectral range. The pulse generation module is configured to adapt the modulation signal to tailor the spectral chirp of the seed light pulses in view of the dispersion characteristics of the compression module, such that propagation of the seed light pulses through the compression module compresses the seed pulses into output light pulses having the target pulse duration.

Abstract: A light stripper assembly for dissipating a residual optical pump power carried by a pump light propagating in an optical fiber component is provided. The optical fiber component includes a pump cladding surrounded by an outer cladding, the outer cladding being removed from the optical fiber component along a lengthwise segment thereof. The light stripper assembly includes a pump stripper disposed about the lengthwise segment and a heat-dissipation packaging structure thermally contacting the pump stripper. The pump stripper includes an input guiding region and a stripping region having refractive indices lower and higher than the refractive index at the outermost periphery of the pump cladding, respectively, so that the pump light is at least partially guided inside the pump cladding along the input guiding region and stripped from the pump cladding along the stripping region. The heat-dissipation packaging structure absorbs and dissipates the residual power stripped by the stripping region.

Abstract: A laser system based on nonlinear pulse compression and a LMA optical fiber therefor are provided. The LMA optical fiber is configured to amplify seed light pulses and promote the onset of nonlinear spectral broadening. The LMA optical fiber includes a first section having constant core and cladding diameters and receiving and supporting propagation of the light pulses in multiple transversal modes. The first section is configured to suppress high order modes propagating therealong. The LMA optical fiber further includes a tapered second section receiving the fundamental mode from the first section, the core and cladding diameters increasing gradually along said second section so as to provide an adiabatic transition of the fundamental mode. The LMA optical fiber further includes an optional third section having constant core and cladding diameters. Dispersive compression of the light pulses outputted by the LMA optical fiber provides excellent beam quality and high peak powers.

Abstract: Method and system for emitting optical pulses in view of a desired output energy of the optical pulses and a variable external trigger signal, using a laser system having a seed laser oscillator optically coupled to one or more cascaded optical amplification stages. For each amplification stage, a plurality of sets of pump pulse parameters are provided, each associated with specific values of the output energy and the trigger period. Proper pumping parameters associated with the received desired value of the output energy and the trigger period of the received trigger signal are selected for each amplification stage, which is pumped accordingly before a seed optical pulse is launched through the system.
