A detailed schematic of Prof. Chang's attosecond optical pulse generator. In this case, the attosecond pulses are formed by nonlinear interaction with a neon jet
Prof. Chang's attosecond optical pulse generator
Simplified schematic of Chang's attosecond optical pulse generator. Nonlinear interaction of the focused femtosecond pulses with the inert gas in the cell shortens the input pulses by a factor of a thousand.
Chang's new laser system which will generate 5 femtosecond pulses with 150 millijoules energy per pulse
Data contrasting the pulse characterization of Chang's PROOF technique with the standard technique
