Sophisticated laser systems, such OPCPAs, consist of multiple parts, the most essential being the front-end used for its pumping and seeding.

FLINT and PHAROS femtosecond lasers are used for repetition rate locking, e.g., for locking and synchronization to synchrotrons.

Carrier-envelope phase determines the accuracy of high-energy and attosecond science experiments and spectroscopy measurements.

Nonlinear optics deals with various kinds of optical nonlinearities, aiming to identify new and efficient nonlinear materials.

Nonlinear microscopy is a powerful technique for imaging inside living organisms with a submicrometer resolution at millimeter depths.

Time- and angle-resolved photoemission spectroscopy (TR-ARPES) extends conventional ARPES by incorporating femtosecond time resolution.
