Expertise
The Centro de Láseres Pulsados is the key Spanish user facility specialized in high-intensity ultrashort lasers included in the strategic National Roadmap of Unique Scientific and Technical Infrastructures (ICTS). Its main mission is to promote scientific and technological development by offering national and international user access to its laser system VEGA, successfully commissioned in 2017 (the 200 TW VEGA-2), and in 2019 (the PW VEGA-3).
VEGA is offered to users with several modes of operation related to the selection of the synchronized lines, the repetition rate (single-shot, burst or nominal frequency or dividers modes,) and the energy (high or low). Moreover, the users have other complementary systems: a CEP laser system that adds an output of 6 fs pulses to the 30 fs laser VEGA allowing ‘pump-probe’ type experiments using a very short duration VUV or XUV system as a ‘probe’; a Quanta Ray laser system that can be synchronized with VEGA’s repetition rate, delivering 1ns/1J pulses, and a highly specialized metrology bench for analysing the laser beam just before it enters the target area.
Particle acceleration, laser metrology, targetry and diagnostic of ultra-short and high-repetition rate PW-class lasers, and generated secondary sources (electron, proton and betatron X-ray) are the main subject of investigations at CLPU. The scientific division is involved in a research programme encompassing the secondary sources’ development and their employment in high density and intense laser-plasma interactions, material science, detectors’ development, nuclear physics etc…
Expertise in recyclable materials
Apart from offering material characterisation techniques such as PIXE (particle induced X-ray emission), X ray fluorescence and absorption, spectroscopy, scanning electron microscopy and related techniques (Energy Dispersive X-ray spectroscopy, and electron backscatter diffraction) CLPU has extensive experience in the use of reusable detectors suitable for characterizing particle beams at high repetition rate measurements. In addition Vega 3 can be used to study Laser induce Damage threshold and pump probe measurements.

Equipment offered to external users
VEGA is a Chirped Pulse Amplification (CPA) system based on Titanium-Sapphire technology with a unique architecture with three outputs (with different powers) synchronized by a unique front-end.
Complementary equipment to VEGA
The CEP Laser is a 4th generation Femtopower system that offers ultrashort pulses (23 fs after amplifier) and few cycle pulses (5 fs or less after hollow core fibre post-compression) with carrier envelope phase stabilised and energy in the range of mJ. It works a central wavelength around 800 nm, in the near-infrared range; and in a spectral band around 50 nm FWHM (after amplifier) and > 200 nm (oscillator and after compression).
Other Information
The Centro de Láseres Pulsados has other important complementary facilities to VEGA that researchers can use to have a higher control over the performance of their experiments:
- Electro-mechanical workshop, where we can design and produce customized pieces for users’ experimental set-ups.
- ULAMP Service (Ultrashort Laser Applications and Micromaterial Processing), a lab with a fs Spitefire laser system that provides a laser beam specially characterized for micromaterial processing. It supports basically the development in targetry and diagnostic devices.
- Microscopy Unit that has a Scanning Electron Microscope (SEM) and an optical microscope, adding values to the performance of the experiments at CLPU.
