TL;DR: An experimental study of supercontinuum generation in photonic crystal fibers with low-intensity femtosecond pulses provides evidence for a novel spectral broadening mechanism, and peculiarities of the measured spectra demonstrate that the reason for the white-light generation is fission of higher-order solitons into redshifted fundamentalsolitons and blueshifted nonsolitonic radiation.

TL;DR: In this article, the growth methodology for bulk and epitaxial layers, its structural, thermo-mechanical, and optical properties, the Yb 3+ and Tm 3+ spectroscopy, and present laser results obtained in several operational regimes both with Ti:sapphire and direct diode laser pumping using IngaAs and AlGaAs diodes near 980 and 800 nm, respectively.

TL;DR: In this paper, the optical properties of the monoclinic crystal of the ytterbium transition have been characterized and the optical anisotropy of the material has been characterized.

TL;DR: Mode locking of an Yb-doped bulk laser in the 1 microm spectral range using a single-walled carbon nanotube saturable absorber (SWCNT-SA) is demonstrated for the first time, to the authors' knowledge.

TL;DR: Stable and self-starting mode-locking of a Tm:KLu(WO(4))(2) crystal laser is demonstrated using a transmission-type single-walled carbon nanotube (SWCNT) based saturable absorber (SA) using the E11 transition of the SWCNTs for nonlinear saturable absorption.
