A pulse shaper includes a seed laser situated to emit laser pulses, an amplitude modulator situated to receive one or more laser pulse bursts from the seed laser, and a pulse signal generator situated to send a seed pulse signal with a predetermined delay to the seed laser so that the seed laser emits the laser pulses in one or more laser pulse bursts at a selected frequency with each laser pulse burst having a selected number of laser pulses and a selected temporal spacing between laser pulses in the laser pulse burst and situated to send an amplitude pulse signal so that the amplitude modulator adjusts the amplitude of at least one laser pulse in each laser pulse burst.

Fully controllable burst shaping individual pulses from picosecond fiber lasers

High power fiber lasers include large or very large mode area active fibers. Mode preserving pump combiners are situated to counter-pump the active fiber using one or more pump sources. The mode preserving pump combiners preserve single mode propagation in a signal fiber, and such combiners can be identified based on optical spectra, beam quality, or temporal response. Active fibers can also be included in a pump combiner so that the active fiber is splice free from an input end that receives a seed pulse to an output end. Peak powers of over 100 kW can be obtained.
