venteon dual


The venteon dual laser system represents the ideal front-end for broadband few-cycle OPCPA applications. The spectral bandwidth of this laser allows for the generation of broadband sub-5.5 fs pulses as a signal for a subsequent NOPA stage and provides sufficient pulse energy (>30 pJ @ 1030 nm) for seeding an Yb-based amplifier pump stage. The pulses are provided by two separate output ports and are intrinsically self-synchronised with ultra-low timing jitter.

The second output around 1030 nm delivers - without any additional broadening - more than 30 pJ in a spectral bandwidth of 10 nm (FWHM) and is ideally suited as narrowband seed for pump amplifiers. Optionally this output can be ordered pre-amplified, delivering pulses with an energy >1 nJ.

Pump-amplifier seed output:

  • Center wavelength: 1030 nm
  • Spectral bandwidth: 10 nm (FWHM)
  • Pulse duration: <200 fs (Fourier-limited)
  • Pulse energy (free-space, 80 MHz): >30 pJ (>2.4 mW)
  • Pulse energy (fiber-coupled, 80 MHz): >12 pJ (>1 mW)
  • RMS noise (1h): <0.5%
  • FC/APC fiber port at the laser enclosure for easy seed pick-up
  • Pre-amplified for optimal amplifier seeding (optional)
  • Pulse energy (pre-amplified, fiber-coupled, 80 MHz): >1 nJ (>80 mW)

    Pulse durations achieved with optional extra cavity compression
