“…The authors could generate an isolated 220 nm peak in the UV spectrum of about 100 pW and further emission down to 120 nm in a noblegas filled fiber [6]. However, this very interesting design needs a careful alignment by focusing the light into one node of the web with size appreciatively of few microns square [5,6]. Therefore alignment is very critical and potentially unstable.…”

In this paper we report imaged neuronal rat cells in a confocal laser scanning microscope by simultaneous generation of the three requested wavelengths obtained by a UV-extended supercontinuum source. This is to the best of our knowledge that such a measure was performed using a microstructured fiber pumped by a standard Ti:Sapphire laser. We observed efficient UV light generation when a novel pumping scheme was used. The pump wavelength is close to the zero-dispersion wavelength of the fiber first high-order mode and offset axial pumping is used. By tuning the pump wavelength and power level we were able to generate mW-power levels in the visible wavelength interval down and of about hundreds of microwatt in the UV wavelength interval down to 300 nm. The pump alignment was very simple and very stable. We believe that further optimization of pump wavelength, fiber length and fiber zero-dispersion wavelength could generate light well below 300 nm using a simple and stable set-up. To demonstrate the potentiality of this technique we imaged neuronal rat cells in a confocal laser scanning microscope by simultaneous generation of the three requested wavelengths

“…However, a main limitation arises from the large dispersion of silica in the blue and UV spectral region that is quite difficult to compensate by fiber geometry, despite large microstructured fiber design flexibility [4]. Recently, UV light generation was achieved in a Kagome photonic crystal fiber [5]. A Kagome lattice has no core, and an intersection of the supporting planes is enough for guiding light.…”

Hyperspectral (fluorescence lifetime) imaging based on a UV-VIS enhanced supercontinuum source using high-order mode propagation

We report on a new source able to provide probe pulses in the UV visible range and on the demonstration of its application to hyperspectral (fluorescence lifetime) imaging measurements. The source is able to generate UV (down to 300 nm) and blue light exploiting high-order mode propagation in a microstructured fiber pumped by a Ti:Sapphire laser. We believe that further optimization of pump wavelength, fiber length and fiber zero-dispersion wavelength could generate light well below 300 nm using a simple and stable set-up and become a useful tool for biomedical imaging. We demonstrated its versatility using the source for FLIM-FRET measurement a 460 nm and hyperspectral FRET-FLIM measurements.
