Paper Abstract

High power and high repetition rate femtosecond lasers are crucial tools furthering the scientific development across many fields. So far, these systems have been realized by Ti:Sapphire lasers at 800 nm, being limited in power scaling. A novel optical parametric chirped-pulse amplifier (OPCPA), pumped by high-power Yb-doped solid state lasers, and combined with bulk crystal white-light-generation seeding (WLG) allows to circumvent the limitation in average power. The presented laser system features carrier-envelope phase (CEP) stable sub 20 fs pulses centered at 800nm with millijoule pulse energies and average power of 20W while remaining on a compact footprint. Such systems have recently become commercially available from Class 5 Photonics and allow for scalability beyond millijoule pulse energies at up to 100W average power.
