We report the results of
experimental study of a white-light supercontinuum generation in
single-mode air-silica microstructured fibres under sub-nanosecond
single and dual wavelength pumping. We show that simultaneous
excitation of the microstuctured fibre in its normal and anomalous
dispersion regimes using the fundamental and second harmonic
signals of a passively Q-switched microchip laser results in
extension of the spectral range covered by homogeneous
supercontinuum to the UV range up to 375 nm.

Eksperimentiškai tirtas superkontinuumo
generavimas vienmodžiuose fotoninių kristalų šviesolaidžiuose
kaupinant vieno ir keleto bangos ilgių subnanosekundiniais šviesos
impulsais. Kaupinant fotoninių kristalų šviesolaidį anomaliosios
ir normaliosios šviesolaidžio dispersijos srityse pasyviai
moduliuotos kokybės mikrolazerio pagrindine ir antrąja
harmonikomis buvo pasiektas spektrinis superkontinuumo išplitimas
į UV sritį iki 365 nm.
