Title: Study of the properties of ultra-short femtosecond pulses Author: Karol Hamráček Department: Department of chemical physics and optics Supervisor: doc. RNDr. František Trojánek, Ph.D. Abstract: Even as a bachelor thesis, the ultra-short pulses produced by the Rainbow CEP4 PRo laser system are about 7 fs long. This implies a very wide spectrum of these pulses, which can be up to 300 nm wide. This is why the ultrashort pulse will be lengthen by passing through a common dispersive medium such as the optical system of the classical optical elements, since each wavelength in the spectrum will propagate differently in the environment and will therefore overtake each other, resp. they will lag behind each other. Our aim will be to study this issue and to deal with the behavior of ultra-short pulses in different media. Keywords: ultra-short pulse, UV area, second harmonic wave
