We have developed a universal and digital pulse driver, that can be remotely operated from a simple computer. This is the ideal tool for driving any valve for gas jet puffing in particular.
Laser Beam Shaping&Metrology
With this new model of the INSIGHT series, two great improvements in user experience have been achieved:
- the acquisition time for mapping the complex E-field of the pulse is reduced by a factor 3. This is particularly relevant for very energetic laser of high peak power operating at low rep rate.
- Quadro can be implemented after your focusing optics (standard mode of operation of INSIGHT) and directly with a collimated beam thanks to a specially designed objective installed at the entrance of the instrument. This greatly enhances the interest of this innovative tool for Research, as the same instrument can now be used not only in the target area, but also anywhere else in the laser area, in particular on a typical bench of diagnostics.
Laser Beam Shaping&Metrology
SourceLAB and the Institute for Basic Science (IBS) are proud to announce the commercial kick-off of the TIPTOE, based on a technique recently developed at CoReLS lab (South Korea). TIPTOE is a spectrally broadband (200nm – 20µm) cross-correlator based on tunnel ionization, that enables to plot the exact temporal profile of the electric field of a laser pulse, without sign ambiguities. In particular, it is well-adapted for the mid-IR spectral range where no equivalent exists so far
We have successfully built an innovative gas cell for laser plasma science, comprizing fast (~3ms) open/close gates at extremities to ensure a very limited gas load in the vacuum chamber at each laser shot. The cell can be adjusted in length on-line, then filled by a gas pressure regulator piloted by the user.
SourceLAB, in collaboration with Phasics and Onera (France), have identified a very interesting regime of operating gas jets for laser plasma interaction. In this regime, a jet from a shock nozzle (SL-Noz Comp) is probed at early instants of the flow with a 20µs time resolution. Thin and well localized density peaks can be observed at some specific height above the nozzle. Focussing an intense laser in such peaks can be quite beneficial for laser plasma acceleration.
SL-GT-10 : High density gas jet
The SL-GT-10 is now operated with an improved Graphic User Interface with precise sub-panels (delay and trigger, dynamic gas line), and adjustable charts mode for pressure monitoring over several hours.
Laser Beam Shaping & Metrology
Our new tool for advanced metrology and mapping of spatio-temporal couplings (STC) at the laser focus was successfully implemented to completely characterize for the first time a PetaWatt femtosecond laser operating at full intensity.
SL-GT-10 : high density gas jet
We have successfully demonstrated in our lab the production in a stable and reproducible regime of a very sharp and high density helium jet. The jet size is <30 µm FWHM, and reads atomic peak density close to 5 x 1020 atoms/cm3. This is a factor five improvement in size comparing to our precedent record in thin and dense gas jet production. We believe this important step forward will benefit in particular to electron injection in laser wakefield acceleration, ion acceleration in near-critical regime and HHG with mid-IR drivers.

SmartShot: an easy access to medium densities range
SourceLAB and our partner Smartshell are proud to propose the smartshot jet system, ideal for reliable laser wakefield acceleration of electron. The wave-free supersonic pulsed gas jet system SMARTSHOT is developed as a gas target for laser-plasma interaction studies such as laser-plasma acceleration, X-ray lasers, laser-plasma X-ray sources, etc…
It can be used for the experimental studies which require the production of very localized high-density gas target with high repetition rate in vacuum.
KAIO : the first plug & play laser plasma accelerator for beam applications
We are pleased to introduce our Kit All In One, a unique powerful tool for ion acceleration and “on-target / high-flux” laser monitoring. KAIO users can accelerate ions with an intense laser, study the related physics and make benefit of the stable ion beam for direct applications (e.g dosimetry, hardening, surface analysis).
With TNSA proton signal from KAIO, users have unambiguous and quantitative access to laser pulse quality (e.g. temporal contrast) and are empowered to improve their laser to suit laser plasma requirements.
SL-ALC: the motorized and adjustable gas cell for LWFA has now its dedicated pressure regulator
SL-ALC-HI system is a motorized gas cell of adjustable length, conceived for laser-plasma interaction experiments in underdense regime.
It ensures stable Laser Wakefield Acceleration at high repetition rate. It now comes with a dedicated regulator to operate in pulsed/continuous modes with on-line and real-time control of the gas density inside the cell.
