Abstract
To avoid harmful nonlinear effects in the amplification of short optical pulses, an initial pulse is divided into a sequence of lower-energy temporally spaced pulses that are otherwise identical to the original pulse. The low-intensity pulses are amplified and then recombined to create a final amplified output pulse.
Claims20
A system for amplifying optical pulses comprising:
- a pulse divider for receiving an input pulse of a first energy level to be amplified and dividing said pulse into a sequence of lower-energy pulses;
- an amplifier for receiving said sequence of lower-energy pulses and generating a sequence of amplified pulses;
- and
- a combiner for combining the pulses in said amplified sequence of pulses into an output pulse that is an amplified version of said input pulse.
