Kerr nonlinearity and dispersion characterization of core-pumped thulium-doped fiber at 2 μm.
A nonlinear coefficient of 3.6-4.1 W-1 km-1 and group velocity dispersion of -20 ps2/km of a commercial core-pumped thulium-doped fiber have been evaluated using degenerate four-wave mixing at 2 μm. The anomalous dispersion behavior of the fiber has been confirmed by linear measurements with an all-fiber Mach-Zehnder interferometer (MZI). Additionally, no pum...
متن کامل1.8-μm thulium microlasers integrated on silicon
A key challenge for silicon photonic systems is the development of compact on-chip light sources. Thulium-doped fiber and waveguide lasers have recently generated interest for their highly efficient emission around 1.8 μm, a wavelength range also of growing interest to silicon-chip based systems. Here, we report on highly compact and low-threshold thulium-doped microcavity lasers integrated wit...
متن کاملThulium fiber laser lithotripsy using tapered fibers.
INTRODUCTION The Thulium fiber laser has recently been tested as a potential alternative to the Holmium:YAG laser for lithotripsy. This study explores use of a short taper for expanding the Thulium fiber laser beam at the distal tip of a small-core fiber. METHODS Thulium fiber laser radiation with a wavelength of 1,908 nm, 10 Hz pulse rate, 70 mJ pulse energy, and 1-millisecond pulse duration...
متن کاملThulium-doped silica-based optical fibers for cladding pumped fiber amplifiers
We present preparation and spectroscopic characterization of the Tm-doped fibers with enhanced 3H4 fluorescence lifetime thanks to codoping with alumina. With the alumina content of 10 mol %, the fluorescence lifetime of 58 s was achieved. Using experimentally obtained fiber characteristics, we used numerical simulations to study and optimize for the first time the thulium-doped fiber amplifie...
متن کاملEmission and absorption cross section of thulium doped silica fibers.
A thorough investigation of the emission and absorption spectra of the (3F4,3H6) band in thulium doped silica fibers has been performed. All the basic parameters of thulium in silica have been extracted with the purpose of further analysis in laser and amplifier simulations. The experimental methods used to obtain the scaled cross sections have been carefully selected in order to avoid problems...
