Abstract

Summary form only given. We present the results of our experiments devoted to the investigation of the spectral broadening of femtosecond Cr:forsterite laser pulses in tapered fibers. Unamplified Cr:forsterite laser pulses were coupled into a tapered fiber manufactured by tapering Corning SMF-28 standard telecommunications fibers with a core diameter of 9 /spl mu/m, a cutoff wavelength of 1250 nm, and a numerical aperture of 0.1.
