Triggered picosecond laser platform

ALPhANOV introduces a new triggered picosecond laser platform based on a fully fibered innovative design. This platform enabled the development of compact, robust and therefore reliable lasers, at a very affordable cost.

 

The technology offers triggered picosecond pulses generally synchronized on TTL signal: this provides a more versatile operation than picosecond mode-locked lasers.

 

This platform is optimized to provide efficient frequency conversion and thus allows laser sources to operate at 1064, 532 or 355 nm, with pulse widths of less than 100 ps. Tests have also demonstrated operation with pulses of shorter duration down to femtosecond, still with a fully fibered deign and with a synchronized trigger.

he combination of high average power (above 50 W), high repetition rate (up to 2 MHz) and pulse energy of up to 50 μJ leads to a family of sources dedicated to numerous applications including: industrial machining for photovoltaic applications, selective ablation, cutting glass or LEDs; nonlinear optics via nonlinear crystals or fibers (supercontinuum generation, for instance).

TresClean

Development of antimicrobial surfaces by high power ultra-short laser texturing.

 

About the project:

 

Goal of the TresClean project is to develop innovative functionalized surfaces by laser texturing, removing the need for chemical treatments. These functionalized materials will find a wide range of applications where self-cleaning and aseptic surface are necessary, such as food packaging and household appliances industries. The processes developed in the frame of the TresClean project will meet the industrial needs especially in terms of productivity with texturing speeds up to 40 mm/s.

 

ALPhANOV's role:

 

ALPhANOV will contribute by developing LIPSS-based texturing laser processes able to adjust the wettability and the antibacterial properties of the treated surfaces. In order to achieve high processing speeds, a sub-picosecond laser system delivering up to 350 W of average power at a high repetition rate (a few MHz) will be employed. The high average power laser system will be connected to a high-speed polygonal scanning head, developed within the project by RAYLASE AG, which will allow the laser beam to move at speeds over 100 m/s.

GRADIOM

 

About the project:

 

The GRADIOM project is the following of the GRAVITER project, which led to the development of a new generation of highly efficient external enhancement-cavity doublers at 780 nm, which was later patented with Muquans.

 

The first step of the GRADIOM project consists to improve the optical performance of this doubler to 780 nm in order to obtain several watts and to enable multiphotonic Raman transitions and thus open the way for the implementation of atomic interferometers with a considerably increased area.

 

The second mission of this project is to use its skills to access shorter wavelengths, especially around 461 nm for strontium atom cooling applications.

 

The last part will be devoted to prospective studies to reach the area of ultraviolet around 390 nm or 399 nm.

 

ALPhANOV's role:

 

Develop single-frequency laser sources by cavity-frequency doubling to access specific wavelengths of atomic transitions: 780 nm, 461 nm, 390 nm.

LASHARE

Share knowledge on laser-based equipment and its use throughout the value chain

 

About the project:

 

LASHARE is an European project, bringing together 32 SMEs and six research centers. They are among the most renowned ones in the field of industrial laser applications.


The objective of the project is to gather and develop knowledge about industrial laser systems and their use throughout the value chain in order to improve productivity and online control of manufacturing processes ... This sharing will allow the approach of the whole value chain. The transformation of innovative solutions from laboratories into industrial products and the dissemination of their use in industry are at the heart of the project. These are key success factors for European manufacturing.


The LASHARE project is divided into several LEAs (Laser Equipment Assessment), each of which involves different operators including a laser equipment supplier, an industrial user and a research partner. This cohesion makes it possible to move from a validated laboratory technology to a sufficiently mature equipment for industrial use.

 

ALPhANOV's role:

The LASHARE project involves several phases. During the first phase (September 2013 - September 2015), ALPhANOV was engaged in two LEAs: TEETO and FEMPAR.

 

A call for projects was launched in February 2015. Following this, ALPhANOV embarked on the second phase of the LASHARE project within 2 LEAs: LASAO and SCALP.

  • TEETO develops laser-based equipment for processing of thin films with a sub nanosecond laser source.
  • FEMPAR develops laser-based equipment to engrave dies for the production of coins.
  • LASAO aims to validate a closed loop control wave front correction system.
  • SCALP aims to validate a 3D laser scanning and laser cutting system for the production of vehicles for disabled drivers.

 

Partners: A total of 68 partners.
In the LEA, LASAO and SCALP:

  • TEETO: Teem Photonics and Micel
  • FEMPAR: Amplitude Systèmes and Monnaie de Paris
  • LASAO: Imagine Optic and Argolight
  • SCALP: ACA and Faro Europe

HELIAM

Develop and commercialize an innovative system allowing the metallurgical processing of parts intended for aeronautics by laser shock.

 

About the project:

 

The HELIAM (High Energy Lasers for Improved Aeronautic Materials) project, approved by the Route des Lasers in 2013, aims to develop and commercialize an innovative process based on the laser shock peening of metallic parts mainly for the aerospace market. Absorption on the metal surface or ablative layer of high energy nanosecond pulses rapidly ionizes and vaporizes more of the surface material to rapidly form a plasma. This rapid plasma expansion creates a shock wave that penetrates into the metal, plastically straining the near surface layer to a depth ten times greater than the one achieved by conventional methods such as shot blasting, which consequently enhances the fatigue lifetime and provides resistance to stress corrosion cracking and fretting fatigue. Laser innovation makes it possible to make a significant leap on the LSP technology which becomes portable.

 

ALPhANOV’s role:

 

ALPhANOV's mission is to design and produce a nanosecond fiber driver delivering energies of several hundred μJ at 1064 nm. This beam should also have a spatial profile as close as possible to the diffraction limit and a thorough control of the pulse shapes with a very high dynamic range.

COMPOCHOC

Create a new non-destructive testing - NDT - technology that can lead to easy assembly qualification and control.

 

About the project:

 

Since September 2015, the COMPOCHOC project, steered by RESCOLL, has developed a platform for the non-destructive testing of laser shock bonding (LASAT process).
The LASAT technology notably allows to demonstrate weak bondings or kissbondings and meets the technical limitations of detection of this type of defects with CND methods conventionally used in industry (ultrasound, radiography, shearography, etc.).
The laser shock allows to apply a mechanical stress calibrated at the level of the bonding. In the case of defective adhesions with low adhesion, a detachment is observed, if the bonding is in conformity, no damage is identified.

 

ALPhANOV’s role:


The role of ALPhANOV is to mainly focus on the development of the electronics and the optical chain of the laser’s first stages, which must deliver the pulses of stress of the assembly under test.

MIRACLE

Production of a supercontinuum medium infrared source.

 

About the project:

 

Miracle (Mid infraRed Advanced superContinuum LasEr) is a collaborative project involving the companies Leukos and Le Verre Fluoré as well as ALPhANOV. It aims to develop a supercontinuum laser emitting wavelengths ranging from 2 microns to 5.3 microns with an average power greater than 4 W. Such a source finds its utility in optical detection, spectroscopy, biophotonics, food and chemical analyses.

 

ALPhANOV's role:

 

ALPhANOV is developing a laser emitting a wavelength of 2 μm and operating in pulsed picosecond (ps) or sub-nanosecond (ns) mode. This laser will serve as a pump for the generation of supercontinuum in the fibers developed by Fluoride Glass. The company LEUKOS is the coordinator and the pilot of the project but also the final integrator of the product. Another innovative aspect of this project is the development of silica glass and fluoride glass welding processes, which will be realized by ALPhANOV.
