Here, we report scalable graphene electro–optical modulators for all-fibre pulsed laser applications, promising various applications such as medical treatment, material processing, and spectroscopy.
Nonlinear optical effects are by default weak but they can be enhanced sculpting the resulting spectrally periodic pulses from a fibre laser into an optimal shape.
This paper presents the results of an experimental and theoretical investigation into the phenomenon of ‘striation free cutting’, which is a feature of fibre laser cutting of thin section mild steel. The paper concludes that the creation of very low roughness edges is related to an optimisation of the cut front geometry when the cut front is inclined at angles close to the Brewster angle for th...
We present here designs for a staged implementation of an orbiting debris remediation system comprised of a super-wide field-of-view telescope (EUSO) and a novel high efficiency fibre-based laser system (CAN). Initial proof of concept stages will operate from the International Space Station (ISS) where the EUSO telescope has been designed for operation as a detector of ultra-high energy cosmic ...
Recent research and development on the femtosecond laser has shown that it is a powerful tool for high precision micromachining. However, femtosecond laser-material interaction is fast and complex due to its ultrashort pulse duration. As the laser-induced plasma possesses useful information to understand the physical mechanism of laser processing, we investigate the optical emission during femt...
Abstract We evaluate the rate of absorption an optical nanofibre mode by a Cs atom in electric quadrupole transition. With localised near outer surface nano-fibre, interaction occurs between atomic tensor components and gradients vector field hybrid fibre mode. The is evaluated as function radial position from axis, assuming specific value laser power we use experimentally accessible parameters...
