Femtosecond optics and physics of high-intensity optical fields
A terawatt femtosecond Ti:Sa laser complex generating laser pulses with duration of about 50 fs, energy of about 250 mJ, and repetition frequency of 10 Hz has been created. A wide series of experiments have been accomplished on the complex. These include:
