WebA chirpis a signalin which the frequencyincreases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirpis used interchangeably with sweep signal.[1] It is commonly applied to sonar, radar, and lasersystems, and to other applications, such as in spread-spectrumcommunications (see chirp spread spectrum).

Chirped Pulse Amplification of Lasers College of …
WebThe method of chirped-pulse amplification has allowed the construction of table-top amplifiers which can generate pulses with millijoule energies and femtosecond durations, leading to peak powers of several terawatts. (1 … WebSeveral authors have utilized optical force, through the linearly chirped laser pulses, for slowing down, acceleration [13] and forced rotation [14] of molecules. It is worthwhile to mention that in late seventies, in an experimental study, Bjorkholm et al. [15] demonstrated the phenomena of focusing, defocusing and steering of neutral sodium ... great power tv
