Features

  • 189 nm – 20 μm tuning range

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

The standard TOPAS-PRIME-HE model accepts pump pulse energy of up to 8 mJ @ 35 fs (up to 20 mJ @ 100 fs), while TOPAS-PRIME-HE-PLUS accepts higher pump pulse energy, up to 18 mJ @ 35 fs (up to 47 mJ @ 100 fs). The pump pulse energy of 60 mJ is possible with longer pulses, ca. 150 fs. Both models come with wavelength extension options, covering the wavelength range from 189 nm to 20 μm for TOPAS-PRIME-HE and 240 nm to 20 μm for TOPAS-PRIME-HE-PLUS.

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

  • 800 nm wavelength
  • 6 mJ pulse energy
  • 1 kHz repetition rate
  • 30 – 40 fs pulse duration
  • Gaussian beam

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

Note 2: TOPAS-PRIME-HE output pulse energy scales linearly in 3 – 20 mJ range, provided the device is installed and optimized for particular pump energy. The device has to be re-optimized if the pump energy changes more than 10% from the installation value.

TOPAS Idler (1600 – 2600 nm) is passively CEP locked due to a three-wave interaction. However, a slow CEP drift may persist because of changes in pump beam pointing or environmental conditions. Such a drift can be compensated by employing an f-2f interferometer and a feedback loop controlling the temporal delay between seed and pump in the power amplification stage of TOPAS-PRIME and TOPAS-PRIME-HE.
