Light Conversion's TOPAS-PRIME-HE is a high-energy femtosecond optical parametric amplifier of white-light continuum for Ti:Sapphire lasers. It is a based on TOPAS-PRIME, featuring an additional high-energy and low-dispersion amplification stage, which allows using up to 60 mJ of pump energy (or even more for custom solutions) and maintaining the shortest possible pulses at the output.
The standard TOPAS-PRIME-HE high-energy OPA model accepts pump pulse energy of up to 15 mJ @ 35 – 60 fs (up to 27 mJ @ 100 – 200 fs), while TOPAS-PRIME-HE-PLUS accepts higher pump pulse energy, up to 35 mJ @ 35 – 60 fs (up to 60 mJ @ 100 – 200 fs). The pump pulse energy of 60 mJ is possible with longer pulses, ca. 150 fs.
Both models come with wavelength extension options, which can cover the maximum wavelength range from 189 nm to 20 μm for TOPAS-PRIME-HE and 240 nm to 20 μm for TOPAS-PRIME-HE-PLUS.
Features
- Pump energy up to 60 mJ
- Energy conversion into the parametric radiation efficiency up to 50 %
- Tuning range spanning from 189 nm to 20 μm, computer controlled
- High output stability throughout the entire tuning range

Note 1:
Pump pulse duration and wavelength affects the specifications. Check the specifications with us if the wavelength or the pulse duration differ from above values.
Note 2:
TOPAS-PRIME-HE output energy scales up linearly in 3 – 20 mJ range, provided the device is installed and optimized for a particular pump energy. The device has to be re-optimized for optimal performance should the pump energy change more than ±10 % from the installation value).
