Starzz
Custom OPCPA systems
Starzz systems are custom-made MIR OPCPA dedicated to High Harmonic Generation (HHG) and attosecond science.
With record CEP stability, high average power or high pulse energy, this new generation of ultrafast light sources combines Yb-doped industrial grade pump lasers with Fastlite landmark technologies to set new standards in ultrafast laser science.
Without the hassle of maintaining a broadband CEP-stable Ti:Sa oscillator up and running, the Starzz systems start from a fiber oscillator and keep a perfect optical synchronization to benefit from passive CEP stabilization. The built-in CEP stabilization loop, based on our exclusive high repetition rate Dazzler and the Fringeezz, adds the extra active control to reach record CEP stability.
To offer superior stability, as well as to make the system alignement and optimization as simple as possible, the twin Starzz is based on an all-bulk dispersion management.
The all bulk stretcher and compressor stages allowed by the exclusive built-in high repetition rate Dazzler, are ideal to reach record CEP stability.
The Starzz systems benefits from the industrial success of Ytterbium laser technology.
Stable and robust fiber oscillators, rugged design, high quality standards, built for non-expert users… Yb-doped systems are the driving power behind our OPCPA systems.
Please contact Fastlite for an offer including a state of the art pump laser, or to check the Starzz performances using your own Yb laser.
Water and CO2 absorption challenges the generation of smooth spectrum and pulses in the MIR. The twin Starzz optical head is sealed, to be operated under dry atmosphere or Nitrogen, and provides clean spectrum and pulses.
Starzz products include the following Fastlite technologies:
| High repetition rate Dazzler ultrafast pulse shaper Exlusively available in our OPCPA systems |
 |
| Fringeezz integrated CEP detector and the CEP stabilization loop |
 |
| Octopuzz synchronization unit |  |
The high-flux/high energy, ultrashort MIR pulses delivered by the Starzz systems open new possibilities in HHG experiments, as they provide the ability to extend the cut-off of the XUV spectra. Coupled with unprecedented CEP stability and high repetition rate, these are unique light sources for imaging, spectroscopy, and attosecond pulse generation.
The Starzz system delivered in the frame of the MIR-OPCPA contract with ELI-ALPS is the first of its kind, and drives research in chemistry, biology, nanoscience, etc… with attosecond resolution.
