Blue extended super continuum light source

摘要: A new blue extended super continuum light source is claimed. When pulses of partly coherent monochromatic 'pump' radiation essentially constant amplitude 5 propagating through a microstructure fibre medium within region anomalous dispersion the medium, then, provided has finite nonlinear coefficient index refraction, pump pulse subject to modulation instability. This instability results in generation and exponential growth sidebands, two closest frequency being dominant ones. The 10 proportional square root power carrier wave. In time domain this leads that interaction between contraction width peaks, which formation train narrow with Tera Hertz repetition rate. 15 Phase match red shifted Raman solitons generated by energy shed at all frequencies group velocity below will lead Cherenkov radiation. or 'light bullets' seed near infrared, visible UV wavelengths depending on actual parameters. extends 20 beyond four wave mixing limit usually experienced when applying picoseconds nanoseconds pulses.
