One of the most sophisticated and intriguing applications of high-energy femtosecond pulses is the process of high harmonic generation.

The main focus of nonlinear optics research is the development of new coherent broadband light sources, as well as novel techniques for pulse compression.

X-ray generation using ultrashort high-energy laser pulses is an attractive technique for producing X-rays that are used in spectroscopy and diffraction measurements.

Terahertz radiation is extensively used to study the dynamics of collective motions in solids and liquids or image optically non-transparent samples.
