INSIGHT Vacuum

This new model of the INSIGHT series makes it possible to directly measure under vacuum Space-Time couplings of laser short pulse. Such a measurement gives access to spectrally-resolved pulse properties very close to what seen by the targetry in real shot conditions. The settings of the laser pulse can thus be optimized according to the desired interaction.

TipToe

ELI-ALPS (ELI hungarian pillar) is using SL-TIPTOE to measure mid-IR ultrashort pulse duration. 4-cycle 120 µJ pulses centered at 3200 nm from a 100 kHz OPCPA system (Black Starzz, Fastlite) were spectrally broadened in millimeter-thick BaF2 and Si windows followed by recompression in CaF2 bulk and custom made dispersive mirrors with negative TOD (Optoman). Pulse duration below 18 fs FWHM (1.7 cycles @3.2 um, 70 µJ) is achieved, successfully measured by TIPTOE. For the reconstruction, a measured spectrum was used.

INSIGHT

A comprehensive experimental campaign exploring Spatio-Temporal Couplings (STCs) on high power lasers.
Spatio-temporal characteristics of various laser chains have been measured with new advanced metrology techniques. Among these powerful techniques, INSIGHT made it possible to reveal for the first time striking STCs that need to be carefully considered for optimal operation and applications of ultrashort laser system.

A key aspect to harness laser plasma electron acceleration is the injection of plasma electrons into the laser wakefield. For the injection, a hydrodynamic shock produced by a blade inserted in a supersonic gas jet, to be ionized into plasma by the laser, is commonly used. Very practically, it is now possible to implement a new class of gas jet nozzles with embedded shocks, without any blade, so as to directly and very reproducibly inject the electrons. The overall setup of the accelerator is greatly simplified.

KAIO

SourceLAB is proud to announce the e-KAIO-kHz, the latest commercial short laser pulse accelerator from our KAIO series.
Integrating most of our unique know-how in targetry and laser plasma technology, e-KAIO-kHz delivers electrons of very high energies at unprecedented repetition rate (up to kHz level).
Thanks to a sound engineering effort in designing this system, users have a fine control in real-time and under vacuum over all critical parameters needed for high-quality particles :

• control of the laser beam alignment in the box
• control of focal plane position
• control of focal spot quality
• control of gas jet position, density and profil
• control of electron spectral dispersion for precise diagnostics
• control of gas load for unlimited operations at kHz rep rate

PulseLAB

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.

INSIGHT Quadro

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.

Tiptoe

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

Gas Cell

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.

Nozzles

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.
