Abstract [en]

Dye lasers, with a gain medium in solid or liquid, or liquid in a solid matrix, states have been a valuable tunable laser source. With the evolution of fabrication techniques the size of the dye lasers has also shrunk to the micro scale. The size reduction has allowed the inclusion of micro cavity dye lasers in novel applications, “lab-on-a-chip” being one of them.

The change in the near field of a fluorophore (the photon emitting part of the dye structure) near the surface of a metal (film or a particle) has been a topic attracting much research, due to its application in inducing an enhancement or quenching of dye fluorescence, a phenomena referred to as metal enhanced Fluorescence (MEF).

In the thesis the effect of MEF due to the introduction of gold NPs to an aqueous Rh6G solution, as a gain medium in a Fabry-Perot cavity dye laser, on the 1) lasing intensity, 2) shift of the lasing spectrum, and the 3) photobleaching time was investigated. The project includes both experiment and simulations. Simulations were employed to visualize the two dimensional energy density pattern of a gold nanorod, and also its interaction with dipole with varying distance between the two.
