Chirped pulse laser
Web3 Ultrashort laser pulses are the shortest technological events ever created by humans. It’s routine to generate pulses shorter than 10-13 seconds in duration, and researchers have generated pulses only a few fs (10-15 s) long. Such a pulse is to one second as 5 cents is to the US national debt. WebOct 5, 2024 · Since the breakthrough – now called chirped pulse amplification (CPA) – many generations of scientists have used the tool in research, Raman says. CPA also facilitated the spread of high-power …
