Chirped cooling
WebJun 25, 2024 · Nature Physics - Laser cooling of optically trapped diatomic molecules CaF to sub-Doppler temperatures has been achieved. The … WebMay 29, 2024 · The term “chirp” refers to the fact that the instantaneous frequency across the duration of the stretched pulse changes, somewhat like the chirp of a bird. Chirped pulse amplification, or CPA, is now the basis on which ultrashort laser pulses are produced.
