Multistability in the laser cooling of atomic beams

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. WebDec 10, 2012 · Spatiotemporal compression of ultrashort pulses is one of the key issues of chirped pulse amplification (CPA), the most common method to achieve high intensity laser beams. Successful shaping of the temporal envelope and recombination of the spectral components of the broadband pulses need careful alignment of the stretcher-compressor … WebJan 13, 2015 · When the chirped pulse is applied in a pure dissipatively coupled optomechanical system, the cooling performance of the … bitwar data recovery 激活碼
