ALPhANOV showcases its latest innovations during the PHOTONICS WEST trade show
January 30, 2013
• A laser module generating picosecond pulses with temporal agility
• A 3D printer laser system for transparent materials
• An innovative femtosecond laser process for nanotexturation
Picosecond laser pulses on demand
Specialized in electronic laser drivers, ALPhANOV recently developed a range
of laser modules called PDM for Pulse-on-Demand Module. This year, the
PDM Pico joins the product family and allows to generate at will pulses from
one hundred picosecond to cw, from a digital input signal. A technological
breakthrough allowing temporal agility sought by industrial actors from different
domains (optics, metrology, semi-conductor testing...)
Nanoscale patterns written in transparent Materials
Recent research has shown that one can form three-dimensional patterns
in glass material (fused silica) using low-power femtosecond laser beam.
FEMTOPRINT, an European project (FP7) gathering 8 partners, aims to develop
a printer for micro-/nano- systems fabricated out of glass. Our ultimate goal is
to provide a large community of users from industry, research and universities
with the capability of producing their own micro-systems, in a rapid manner
without the need for expensive infrastructures and specific expertise. The first
prototype of this system will be shown during the Photonics West exhibition on
the Amplitude Systemes’ booth (#1615), one of the project partner.
LASERS PRODUCE SUPER-BLACK COATINGS
ALPhANOV developed a laser process to turn shiny metals blacker than black.
Based on femtosecond lasers, the process relies on highly intense laser pulses
creating nanostructures at the surface of metals such as stainless steel, gold,
etc. These nanostructures act as a photon trap absorbing all the light that falls
on it. This results in a deep black coating that can easily be shaped to create
various features and patterns with high precision and uniformity.
Generating of fluorescent nanoparticles
The unique properties of the nanoparticles led to many different applications,
whether for the medical field, for traceability or for biological analysis... ALPhANOV
developed a process to produce nanoparticle in liquid media by laser
ablation of a macroscopic meterial allowing to be free from chemical methods.
For the first time, ALPhANOV applied this method to phosphorus «upconverters» (UCP),
photoluminescent materials which re-emitted a visible luminescence
from infrared excitation. These nanoparticles have a high potential for
many applications, especially for biological monitoring or fluorescent marking.
