OPTICAL PARAMETRIC ULTRASHORT PULSE AMPLIFIER

摘要

The invention relates to an optical parametric amplifying device (200), comprising: emitting means (220) for emitting non-monochromatic light pulses, referred to as pumping waves (Sp); a stretcher (250) arranged to receive as input a pumping wave (Sp), and to deliver as output a stretched pumping wave (Spe); and a waveguide (230) arranged to receive as input the stretched pumping wave (Spe) and chirped pulses, and to deliver a wave (SAe) resulting from four-wave mixing.
