Chirp pulse amplification
Did you know?
WebChirped-pulse amplification (CPA) technique has been widely used to generate ultra-intense femtosecond pulses. In this scheme, the seed pulses from an oscillator are stretched before amplification, usually by introducing a positive chirp, and afterwards compressed with an equally large negative chirp[1]. The stretched pulses, WebApr 13, 2024 · This further highlights the necessity of using a taper for broadband chirped pulse amplification. Indeed each signal component will only be amplified in a given portion of length \(L_p\) within the taper of length L. Consequently, adjusting the pump and signal chirp and delay along with a suitable taper variation rate allows more frequency ...
