Laser Outline (click to see)
- Ti:Sapphire oscillator (Femtolaser Rainbow) emitting pulses with a duration of 7 femtoseconds (@780 nm), CEP stabilized. Pulse repetition rate of 78 MHz. A CEP non-stabilized output could be avalaible in parallel operation to the main chain.
- Two loops for CEP stabilization to achive CEP stability down to 200 mrad rms (3 hours).
- Multipass amplifier with an output up to 2 mJ/pulse at 1 kHz repetition rate. After compressor, pulses of around 23 fs (FWHW) are obtained.
- A Dazzler system inside the multipass amplifier controls spectrum and spectral phase.
- Active pointing stabilization before and after the amplifier and before the postcompression stage.
- Hollow core fibre postcompression (Ne) system to achieve 5 fs/0.6 mJ pulses.
Laboratory's Layout (click to see)
The characteristics of the laboratory and the laser sources aim to offer very stable and reliable experimental conditions, as well as a high degree of control on the radiation characteristics.
On the other hand, a broad range of characterisation techniques, both standard and home developed, is offered to the user for a full understanding of the experiments.
High Energy Laboratory
Work Station 01 - High energy
It uses the main amplified beam, at power levels of tenths of GWs or even 100 GW, with pulses of 23 fs and down to 5 fs. Applications such as nonlinear optics, femtochemistry, time resolved spectroscopy, etc. can be carried on at this work station.
Work Station 02 - XUV secondary source
The main amplified beam (prior or after postcompression) can be focused within a gas jet inside a vacuum chamber, generating a spectral comb in the XUV region. This radiation can be used in attoscience, as well as in XUV applications.
Low Energy Laboratory
Work Station 03 - Low energy
The beam used in this area comes from the oscillator or from a small leakage of the CEP stabilization module. It is focused to high repetition rate application, photonics, broadband experiments, etc.
