Where to Buy Optical Parametric Chirped-pulse Amplifiers

Our Starzz systems are custom-made mid-IR OPCPA dedicated to High Harmonic Generation (HHG) and attosecond science. With record CEP stability, high average power or high pulse energy, this new generation of ultrafast light sources combines Yb-doped industrial grade pump lasers with Fastlite landmark technologies to set new standards in ultrafast laser science.

Laser Quantum manufacture the world's first commercially available OPCPA system. Generating a unique combination of few-cycle pulse durations and pulse energies in the μJ regime at high repetition rates, the system can be CEP stabilised without the need for additional spectral broadening.

TOPTICA’s FemtoFiber dichro midIR generates radiation at 3 μm – 15 μm. Based on difference frequency generation of two optically synchronized laser pulses at tunable wavelengths of 1 – 2 μm a highly stable broadband emission of approximately 400 cm^-1 is generated. Here, the output at 1560 nm of an erbium-doped ultrafast fiber laser is superimposed with the long or short wavelength part of a supercontinuum.

The CEO-free mid-IR laser pulses are applied to attosecond spectroscopy where the extreme UV pulses consist of only a few optical cycles. The conversion of mid-IR radiation to extreme UV is accomplished by high harmonic generation. First, the mid-IR pulses are subject to optical parametric chirped amplification (OPCPA). Then, the intense laser fields are launched into an atomic beam or a gas-filled hollow core fibre to generate extreme UV attosecond laser pulses via high harmonics.
