The study of propagation of a femtosecond laser pulse in the breast tissue

In this paper, the evaluation of time profile of a femtosecond pulse laser propagated through biological tissues is studied. The majority of the biological tissues with a high scattering anisotropy must be considered as turbid media, that their optical responses are complicated. To study the propagation of ultra-short pulse in turbid media, the diffuse equation is used. In this study, the analy...

Femtosecond laser pulse shaping in the UV

Quantum control using femtosecond laser pulses has recently induced a revolution in photochemistry. Not only the nuclear motion within a molecule can be observed time resolved, but it can be controlled. The necessary pulse shaping techniques, however, have mainly restricted this control so far to visible and near IR absorptions. Fundamental compounds of organic chemistry and biochemistry such a...

Femtosecond Laser Pulses and Pulse Shaping

The experiments in this thesis have been performed using femtosecond laser pulses at different wavelengths. The second and third harmonic of of the fundamental output (800 nm) of a commercial laser have been used in several experiments. In other experiments laser pulses in the visible were required. A homebuilt non-collinear optical parametric amplifier (NOPA) has been used to generate tunable ...
