Investigation of controlled ultrashort pulse dye laser for femtosecond nonlinear spectroscopy
2014 Characteristics of a simple but practical ultrashort pulse laser system for transient nonlinear spectroscopy around and below 100 fs are described. The system is based on a hybridly mode-locked, cavitydumped cw dye laser, with high stability, broad tunability and specific phase properties, producing both clean transform-limited and chirped pulses. The laser system is applied to demonstrate...
متن کاملPulse propagation near zero group-velocity dispersion in a femtosecond dye laser.
The propagation of femtosecond pulses in a colliding-pulse mode-locked dye laser near zero group-velocity dispersion is studied. The pulse spectrum is shown to exhibit a double-peak structure. This structure and its dependence on the intracavity dispersion can be explained by nonlinear pulse propagation near zero dispersion. A value for the third-order dispersion of the laser cavity is deduced ...
متن کاملFemtosecond 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...
متن کاملFemtosecond 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 ...
متن کاملFemtosecond laser pulse shaping for enhanced ionization
We demonstrate how the shape of femtosecond laser pulses can be tailored in order to obtain maximal ionization of atoms or molecules. For that purpose, we have overlayed a direct-optimization scheme on top of a fully unconstrained computation of the three-dimensional time-dependent Schrödinger equation. The procedure looks for pulses that maintain the same total length and integrated intensity ...
