Supercontinua for high-resolution absorption multiplex infrared spectroscopy.
Supercontinua generated in highly nonlinear fibers by ultrashort-pulse lasers can be used for high-resolution Fourier transform absorption spectroscopy. The practical advantages of these bright ultrabroadband light sources for spectroscopy in the near-infrared region are reported. A Cr(4+):YAG femtosecond laser broadened by an extruded soft-glass photonic crystal fiber, emitting from 1200 to 22...
متن کاملInfrared frequency combs and supercontinua for multiplex high sensitivity spectroscopy.
An infrared high-brightness light source based on supercontinuum generation through a SF6 photonic crystal fiber seeded by a Cr(4+):YAG femtosecond oscillator is developed for high resolution multiplex spectroscopy in the 1.5 μm region. Moreover, a multiplex high resolution approach based on a Cr(4+):YAG frequency comb enables to probe large spectral domains, with simultaneous sensitive measure...
متن کاملHigh resolution imaging with differential infrared absorption micro-spectroscopy.
Although confocal infrared (IR) absorption micro-spectroscopy is well established for far-field chemical imaging, its scope remains restricted since diffraction limits the spatial resolution to values a little above half the radiation wavelength. Yet, the successful implementations of below-the-diffraction limit far-field fluorescence microscopies using saturated irradiation patterns for exampl...
متن کاملHigh spectral resolution multiplex CARS spectroscopy using chirped pulses
A simple technique for achieving high spectral resolution coherent anti-Stokes Raman scattering (CARS) spectra with a femtosecond laser system is presented. A linearly chirped and stretched ( 10 ps) pump pulse generates CARS signal only when overlapped in time with the Stokes pulse (90 fs), creating a ‘temporal slit’ that defines the spectral resolution of the technique. Multiplex CARS spectra ...
