Self-doubling organic laser based on a dye-chromophore mixture

摘要

We report calculations and experimental results on intracavity second-harmonic generation (SHG) using a mixture of an active lasing dye and a nonlinear optical chromophore. By applying a high-voltage electric field across the solution, synchronized with the dye laser emission, the chromophore molecules can be oriented as the laser emission develops, providing SHG of the laser beam. Compared to other approaches, this configuration does not require two separate optical components for the amplification and SHG, simplifying the design and realization of compact near-UV laser sources.
