Michelson-type all-reflective interferometric autocorrelation in the VUV regime
New Journal of Physics, 2014 We demonstrate second-order interferometric autocorrelation of a pulse in the vacuum-ultraviolet (VUV) spectral range using an optical arrangement equivalent to a Michelson interferometer. In an all-reflective design, wavefront splitting is realized with

Higher-Order Mode Suppression in Antiresonant Nodeless Hollow-Core Fibers
Micromachines, 2019 Negative curvature hollow-core fibers (NC-HCFs) are useful as gas sensors. We numerically analyze the single-mode performance of NC-HCFs. Both single-ring NC-HCFs and nested antiresonant fibers (NANFs) are investigated.

From a continuous to a discrete time crystal in a dissipative atom-cavity system
New Journal of Physics, 2020 We propose the dynamical stabilization of a nonequilibrium order in a driven dissipative system comprised an atomic Bose–Einstein condensate inside a high finesse optical cavity, pumped with an optical standing wave operating in the regime of anomalous ...

New Journal of Physics, 2018 We present systematic studies of the transient dynamics of GaAs by ultrafast time-resolved reflectivity. In photoexcited non-equilibrium states, we found a sign reverse in reflectivity change Δ R / R , from positive around room temperature to negative at

Low Loss Hollow-Core Antiresonant Fiber With Nested Elliptical Cladding Elements
IEEE Photonics Journal, 2017 We design and investigate the optical properties of a novel hollow-core antiresonant fiber with nested elliptical cladding elements. This new structure shows low confinement loss even with a relatively small core.

A 5.32 mJ and 47.5 kW cavity-dumped Pr3+:LiYF4 pulsed laser at 639 nm
High Power Laser Science and EngineeringIn this work, we confirm a Pr3+:LiYF4 pulsed laser with high power and high energy at 639 nm based on the acousto-optic cavity dumping technique. The maximum average output power, narrowest pulse width, highest pulse energy and peak power of the pulsed ...

Sub-40 fs Pulses from a Tapered Yb-Doped Fiber Amplifier with Self-Similar Amplification
PhotonicsWe extended self-similar amplification to a large-mode-area tapered Yb-doped fiber (LMA T-YDF) with longitudinally decreasing nonlinearity. The theoretical analysis and numerical simulation demonstrate that T-YDFs with different nonlinearity profiles can
