  • Excellent long-term average power stability: ≤ 1.5 % RMS over 8-hour period
  • Perfectly synchronized fs and ps output option available
  • Hands free wavelength tuning
  • High contrast pulses without any additional improvement equipment

Applications

  • Broadband CARS and SFG
  • Femtosecond pump-probe spectroscopy
  • Nonlinear spectroscopy
  • High harmonic generation
  • Wake field particle acceleration
  • X-ray generation

High Energy UltraFlux laser series delivers up to 25 TW peak power operating up to 10 Hz. Originally built for ELI‑ALPS (Extreme Light Infrastructure – Attosecond Light Pulse Source) in Hungary, this series is now available for a wide variety of applications.

The master oscillator is a patented (no. EP2827461 and EP2924500) all-in-fiber Yb doped picosecond laser seed source with two fiber outputs. One seeds the OPCPA Front-End and another seeds the Picosecond Pump Laser. Both outputs originate from the same fiber so they are optically synchronized.

This approach eliminates the need for a complex temporal synchronization system typically present in other OPCPA systems.
The Nd:YAG Picosecond Pump Laser system (PPL) is comprised of several sub-systems: diode pumped Regenerative Amplifier, diode pumped Preamplifier, flash lamp pumped Amplifiers, and Second Harmonic Generators which convert fundamental 1064 nm wavelength to 532 nm. PPL outputs multiple beams at 532 nm. One beam is directed to NOPCPA Front-End subsystem and others are directed to NOCPA amplification stages.

The Front-End NOPCPA (Non-collinear Optical Parametric Chirped Pulse Amplifier) consists of several sub-systems: Picosecond Optical Parametric Amplifier (ps-OPA) amplifying oscillator output pulses, Grating Compressor compressing ps-OPA output pulses, White Light Generator (WLG) broadening the spectrum of ps-OPA output pulses and Femtosecond Non-collinear Optical Parametric Amplifier (fs‑NOPA) amplifying WLG output pulses.

The Stretcher sub-system is a Grism (diffraction gratings combined together with prisms) or Offner type pulse stretcher, which stretches output pulse from NOPCPA Front-End and Dazzler (optional Acousto-Optic Programmable Dispersive Filter) for high order phase compensation.

Multiple stages of NOPCPA (Non-collinear Optical Parametric Chirped Pulse Amplifiers) are used to amplify the stretched pulse from the Stretcher up to 1 J.

Finally, amplified pulses are compressed back down to fs duration in the Pulse Compressor. Bulk glass compressor (combined together with chirped mirror) or traditional diffraction grating compressor can be used depending on pulse duration required and output energy level.

The built-in Output Diagnostics stage ensures reliable, turn-key operation by monitoring critical parameters such as energy, duration, and beam profile.
