What “ultrafast” means
Wiktionary · Wikipediaultrafast
- adjectiveVery fast, or of very short duration; especially concerning events that take place in femtosecond or picosecond timescales.
In optics, an ultrashort pulse, also known as an ultrafast event, is an electromagnetic pulse whose time duration is of the order of a picosecond or less. Such pulses have a broadband optical spectrum, and can be created by mode-locked oscillators. Amplification of ultrashort pulses almost always requires the technique of chirped pulse amplification, in order to avoid damage to the gain medium of the amplifier.
