Chirp cooling

Webresonant frequency (as in so-called chirp cooling) [3], and methods that use this approach only produce pulsed sources, one instead uses magnetic fields and the Zeeman effect to tune the atoms Œ that is, to change their resonant frequency in a way that compensates for the change in speed and keeps them continually on resonance. WebChirped pulse amplification ( CPA) is a technique for amplifying an ultrashort laser pulse up to the petawatt level, with the laser pulse being stretched out temporally and spectrally, then amplified, and then compressed again.
