EXTREME LIGHT PULSE-FRONT TILT AND ITS APPLICATION TO SINGLE SHOT MEASUREMENT OF PICOSECOND TO NANOSECOND LASER PULSES

摘要

Various methods and systems are provided for generation of a laser pulse with massive pulse-front tilt (PFT) and its use for measurement of laser pulses. In one embodiment, a method includes directing a laser pulse into an etalon and propagating the laser pulse through the etalon to form a tilted pulse. Another embodiment involves directing pulses into an etalon and propagating the pulses through the etalon in opposite directions to form a pair of massively tilted pulses that are tilted in opposite directions. In another embodiment, a system includes a Fresnel biprism configured to produce a pair of pulses from an input pulse and a lens configured to direct each pulse through an opening (or openings) in an input surface of an etalon, where the etalon is configured yield a pair of pulses tilted in opposite directions, each pulse having a massive PFT.
