High-energy Ti:sapphire laser system at 1 kHz optimised for efficient frequency conversion

Over the past two decades significant progress was made in generation of high peak power ultrashort pulses utilizing the chirped pulse amplification (CPA) technique. Sub-30-fs pulses with more than 12 mJ energies at 1 kHz repetition rate were generated using Ti:sapphire CPA laser systems. We developed a high-energy Ti:sapphire CPA laser system delivering up to 12 mJ pulses with sub-100-fs duration and spectral bandwidth of 13 nm.
