Abstract

We have successfully developed a high-energy, high-repetition rate Ti:sapphire laser system that delivers 33J before compression at 0.1Hz. The final booster amplifier is based on a 100mm diameter Ti:sapphire crystal pumped with 72J of energy in six beams delivered by three frequency-doubled high-repetition rate Nd:glass lasers. This system is, to the best of our knowledge, the first demonstrated petawatt class laser system running at a high repetition rate.
