Abstract
The ASACUSA collaboration has developed injection-seeded Ti:sapphire lasers of linewidth Γpl ∼ 6 MHz, pulse energy 50–100 mJ, and output wavelength λ = 726–941 nm. They are being used in two-photon spectroscopy experiments of antiprotonic helium atoms at the Antiproton Decelerator (AD) of CERN. Ti:sapphire lasers of larger linewidth Γpl ∼ 100 MHz but more robust design will also be used in collinear resonance ionization spectroscopy (CRIS) experiments of neutron-deficient francium ions at the ISOLDE facility.
