ULTRABROADBAND LASER USING PRISM-BASED SPATIALLY-DISPERSIVE RESONATOR

An ultrabroadband (up to 35 nm FWHM) generation by a pulsed dye laser is reported. The principle of laser operation is based on a recently proposed cavity configuration, which we have termed "spatially-dispersive" resonator. By means of a prism pair this spreads the various spectral components into different spatial areas in the active medium and thus reduces the competition between them. A generation of a spectrum containing a number of equally spaced lines is also demonstrated. © 1990 Springer-Verlag.
