Two implementations were planned for the already existing SPARC_LAB infrastructure within the SABINA project. One of these involves using a powerful laser to generate high-intensity pulses. Taking advantage of the experience acquired in the National Laboratories of Frascati over the years, the project’s goals are to strengthen the instrumentation to guarantee stability and precision for users from the aerospace sector to the study of materials.
This second line will be a unique irradiation facility in Italy as well as competitive on the international scene. It will provide pulses of light at different wavelengths and different peak power levels to perform tests on samples such as vacuum optics used in the aerospace sector.
A peak power of approximately 250TW can be achieved at a wavelength of 800nm (with a bandwidth of over 60nm), a repetition rate of 5Hz, a minimum duration of 25fs, and a maximum energy before compression of 6J.
In practice, there may be different test areas available: a first area in which a narrow band 532nm line will be made available (5J, 5Hz), a second area in which the long infrared beam will be made available (6J, 5Hz) and a final area where it will be possible to perform vacuum tests with the laser at maximum power (4J, 1-5Hz).
This opens the door to users with different backgrounds, from aerospace to industrial research.
