Femtosecond 100 W-level OPCPAs from near-IR to short-wave-IR wavelengths

A review of current high power (100 W-level), femtosecond, optical parametric chirped-pulse amplifiers (OPCPA) at near IR (NIR) and short-wave IR (SWIR) wavelengths pumped by Yb-based solid-state lasers is presented. OPCPA technology together with white-light-generation (WLG) makes it possible to provide CEP-stable femtosecond broadband or tunable pulses (from 700nm to 2.1 μm), which are potentially scalable to much high power levels. An important feature of these new OPCPAs is their reliability and compact design, requiring no complex cooling systems.
