High power and high repetition rate lasers are critical for many applications in the physical, chemical, and biological sciences. Previously, laser sources from x-ray to THz were driven from Ti:Sapphire lasers at 800 nm with limited bandwidth (Fourier limited pulse of 20 fs), and more importantly limited power levels; power levels 40 W and above require large complex cooling systems. Optical parametric chirped-pulse amplification (OPCPA) together with bulk crystal white-light-generation (WLG) opens up the possibility of high power lasers (well above 100 W), with wavelength tunable and broadband (for example, < 10 fs at 800 nm), requiring no complex cooling with a compact design. Recently, 100 W-level OPCPAs are now commercially available from Class 5 Photonics GmbH from 800 nm to 2 µm.
