Femtosecond laser system UltraFlux HE

fiberindustrialfor spectroscopy

The UltraFlux HE series is a high energy femtosecond OPCPA (Optical Parametric Chirped Pulse Amplification) laser system designed for demanding scientific and industrial applications. Delivering up to 30 TW peak power at up to 10 Hz, it was originally developed for ELI‑ALPS (Extreme Light Infrastructure – Attosecond Light Pulse Source) in Hungary and is now available for a wide range of uses. The system is based on patented OPCPA technology and features a master oscillator that is an all-in-fiber Yb doped picosecond laser seed source with two fiber outputs, ensuring optical synchronization and eliminating the need for complex temporal synchronization systems. The Nd:YAG Picosecond Pump Laser system includes diode pumped and flash lamp pumped amplifiers, as well as second harmonic generators for wavelength conversion. The Front-End NOPCPA consists of several subsystems, including a picosecond optical parametric amplifier, grating compressor, white light generator, and femtosecond non-collinear optical parametric amplifier. The system uses a grism or Offner type pulse stretcher and a Dazzler for high order phase compensation, with multiple amplification stages to achieve up to 1 J pulse energy. Amplified pulses are compressed to femtosecond durations, and output diagnostics ensure reliable, turn-key operation.
