TOPAS-PRIME-HE is a high-energy femtosecond optical parametric amplifier (OPA) based on TOPAS-PRIME, featuring an additional high-energy and low-dispersion amplification stage, which allows using pump pulse energies of up to 60 mJ while maintaining the shortest possible output pulse.

  • TOPAS-PRIME-HE accepts pump pulse energies of up to 15 mJ at 35 – 70 fs (up to 27 mJ at 100 – 200 fs).
  • TOPAS-PRIME-HE-PLUS supports higher pump pulse energies, up to 35 mJ at 35 – 70 fs (up to 60 mJ at 100 – 200 fs). The 60 mJ pump pulse energy is achievable with longer pulse durations, around 150 fs.

Both models include wavelength extension options:

  • TOPAS-PRIME-HE: Tunable from 189 nm to 20 μm.
  • TOPAS-PRIME-HE-PLUS: Tunable from 240 nm to 20 μm.

Ultrafast (20–70 fs)
Specifications notes

TOPAS-PRIME-HE and TOPAS-PRIME-HE-PLUS specifications are given for the following pump laser parameters:

  • Wavelength: 800 nm
  • Pulse energy: 6 mJ
  • Repetition rate: 1 kHz
  • Pulse duration: 30 – 40 fs
  • Beam profile: Gaussian

Note 1: Specifications depend on the pump wavelength and pulse duration. If these differ from the values listed above, contact  sales@lightcon.com.

Note 2: TOPAS-PRIME-HE output pulse energy scales linearly within the 3 – 20 mJ range, provided the device is installed and optimized for a specific pump energy. Re-optimization is required if the pump energy changes by more than 10% from the installation value.

Performance
CEP Stabilization of Idler

The Idler of TOPAS (1600 – 2600 nm) is passively carrier-envelope phase (CEP) locked due to the three-wave interaction process. However, a slow CEP drift may occur as a result of pump beam pointing fluctuations or changes in environmental conditions. This drift can be compensated by employing an f-2f interferometer combined with a feedback loop, which controls the temporal delay between seed and pump in the power amplification stage of TOPAS-PRIME and TOPAS-PRIME-HE.
