Hello to all,
In a short pulse laser emission setup, can a pulse be emmited with beam length shorter than one wavelenght? (can a pulse have a duration shorter than its period?)
Lets say a laser emmiter shoots a quarter cycle pulse, what would happen to this short beam?
(lets supose the existence of a very fast chopper, and a very agile laser emmiter on the setup)EDIT:
I've found another thread within this subject (couldn't find it before):
