Improved line narrowing and wavelength stabilization technique of distributed feedback dye lasers
Abstract
A new method is described, for the wavelength stabilization and line narrowing of DFB dye lasers, using a dispersive pumping arrangement, where the wavelength shift of pumping light is compensated by a change in the incident beam angle. A predicted relation between pumping wavelength shift and DFB laser wavelength shift is verified experimentally. A twentyfold line narrowing in comparison with pumping linewidth, is realised in a preliminary experiment.
