LabCom Starlight+

PIs: Giorgio Santarelli (LP2N), Nick Traynor (ALS).
Associated permanent members: Germain Guiraud (ALS), Adèle Hilico (LP2N), Y. Bardin (ALS), M. Goeppner  (ALS).
The joint laboratory Starlight+ fosters together the skills of the French company AzurLight Systems (ALS) specialized in high power fiber lasers  and the Photonic Systems  group at LP2N for advanced metrology. The target of this team is to tackle technological and fundamental challenges in low noise high power laser systems for industrial and scientific applications.

Graduate students&Postdocs: C. Dixneuf, Dia Darwich.


Starlight+ has been selected by the ANR LabCom Program (ANR LabCom) mid 2014 and started operations beginning of 2015.

After the 3 years initial phase the LabCom has enter in a consolidation phase (ANR LabCom consolidation 2017).

The LabCom is also strongly supported by the Conseil Régional Nouvelle Aquitaine and the cluster of excelelnce Laser& Photonics in Aquitaine (LAPHIA)

The LabCom capitalize on the rich environment for lasers & photonics  in the Aquitaine region and the proximity of ALPhANOV (ALPhaNOV), the technology center of the ALPHA-Rlh ( ALPHA Rlh) competitiveness cluster (Photonics & Microwaves French cluster) which supports innovation in laser &photonics.

Road Map

Stable light sources find applications in many aspects of fundamental research (laser cooling, atomic clocks, quantum computing, atom interfereometry…), but also in an ever increasing number of real-world applications (LIDAR, holography, industrial instrumentation, high resolution spectroscopy for pollutant detection,….), where fine control of amplitude, frequency and phase is extremely important.

This  joint laboratory  aims to the creation of a new class of stabilized fiber lasers exhibiting unparalleled power, frequency stability and wavelength agility.  The scientific program is organized around three main research themes:


  • Study of laser noise properties and development of new stable laser systems based on MOPA fiber architectures in the spectral range from 976 – 1120 nm.
  • Development of systems for laser stabilization and frequency control, optimized specifically for fiber laser architectures.
  • Development of new architectures for agile lasers systems suitable for precise frequency sweeping in the visible and Deep Ultra Violet spectral regions using optimized resonant frequency conversion schemes.


The LabCom Team has demonstrated a low-noise and high-power (17W) continous wave green source by single pass frequency doubling of a 1064 nm laser (C.  Dixneuf et al, 10.1364/OL.415532)
