Guarantee: 'prof. RNDr. Ondřej Haderka, Ph.D.'

Annotation: The lecture aims to understand properties, ways of generation, and amplification of optical pulses in the range from milisecond to femtosecond pulses.

Course review:
1) Generation of milisecond laser pulses - free running regime 2) Generatin of nanosecond pulses - Q-switching, gain switching, cavity dumping; rate equations 3) Generation of picosecond and femtosecond pulses - mode-locking technique (active, passive, Kerr-lens mode-locking) 4) Properties of femtosecond laser pulses, dispersion, pulses shaping, pulse stretching and compression 5) Ultrashort laser pulse diagnostics (autocorrelation, FROG, SPIDER etc.) 6) Laser pulse amplification - regenerative and multipass amplifiers, gain saturation 7) CPA technique (chirped pulse amplification); high power laser systems; optical isolators and spatial filters, XPW 8) Tunable lasers. Nonlinear light scattering - Raman lasers 9) Nonlinerar phenomena of second and third order - optical parametrical generation and amplifiacation (OPG, OPA) 10) Self-focussing, self-phase modulation, supercontinuum generation. OPCPA technique, periodically-polled crystals
