Femtosecond absorption spectroscopy for study of stimulated emission
 Streshkova, Neli ; Malý, Petr (advisor) ; Zukerstein, Martin (referee)
The aim of the thesis is the building and optimization of an experimental setup for me- asuring the transient transmission and optical gain by the femtosecond pump and probe technique. The setup combines the technology of parametric generation of pump pulses with tunable wavelength and the generation of femtosecond continuum as a spectrally wide probe. In the thesis, conditions of supercontinuum generation in bulk fused silica are extensively studied from a practical viewpoint. The performance of the setup was tested on two types of samples: the solution of rhodamine 6G in methanol and the semiconduc- tor nanocrystalline sample - CdSSe-doped glass. Time resolved spectra of the transient transmission of both samples were measured and the spectral dependence of the optical gain in rhodmine 6G was obtained. 1
