For example, the lasers used at INRS produce ultrashort pulses in the femtosecond range (10 exp -15 s) that are far too short to visualize.

The interaction between extremely powerful laser pulses and matter has opened up entirely new approaches to the generation of ultrashort light flashes lasting for only a few hundred attoseconds.

As these narrow waveguides (~1-3 µm core diameter) are combined with ultrashort pulses at the zero-dispersion wavelength pulses are not instantly destroyed by dispersion.

Extremely high powers in ultrashort pulses can be achieved with Yb:YAG.

He developed a method using a rapid laser technique (consisting of ultrashort laser flashes), which allows the description of reactions at the atomic level.

It is also notable for use as a mode-locked laser producing ultrashort pulses of extremely high peak power.

These devices can generate high power outputs with good beam quality, wavelength-tunable narrow- linewidth radiation, or ultrashort laser pulses.
