Abstract
An injection-seeded high-repetition rate (∼10 kHz) Ti:sapphire laser with a spectral bandwidth of ∼20 MHz and an average output power of above 1.5 W has been developed. We report on its demonstration and characteristics with respect to the spectral, temporal, and spatial properties as well as the output energy. In crossed-beam resonance ionization on a well-collimated thermal atomic beam, the ∼200 MHz hyperfine structure of the D2 transition at 308 nm of 27Al has been well resolved. Applications of the system in the field of insource laser spectroscopy for on-line produced short-lived radioactive isotopes as well as for selective-trace isotope determination are discussed.
