Diagnostic appliances and setups for femtosecond spectroscopy

Generation and application of the ultrashort laser pulses is one of the modern trends in photonics. The application of the high-power ultrashort laser pulses allows one to incredibly concentrate electromagnetic energy in time and space, which makes it possible to observe new nonlinear optical phenomena (self-focusing, phase self-modulation, generation of optical harmonics of high order, etc.). In addition, the high-power femtosecond laser pulses can help in precise microprocessing of the materials.
