The Nd:YAG laser | CO₂ laser

The ATF has presently two lasers:a Nd:YAG laser and a Terawatt CO₂ laser. A new Ti:Sapph laser is under installation. The Nd:YAG laser produces controlled mode-locked train of 15-ps FWHM, 30-mJ pulses at a 3 Hz repetition rate. One pulse from this train is directed through second and, then, fourth harmonic crystals to a photocathode generating ~10 ps electron bunches at a photoinjector for the 70-MeV linac.

Another pulse selected from the same train controls an optical switch to produce a 5-ps seed pulse for CO2 laser amplifiers. Amplified to the Terawatt peak power, the CO₂ laser beam is used for various experiments. Many of them are based on interaction between the laser and electron beam. Originating from the same mode-locked train allows necessary for such experiments absolute synchronization between the electron- and CO2 laser pulses.

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
