Light Conversion's HE‑TOPAS‑Prime is a 3‑stage femtosecond optical parametric amplifier of white-light continuum. It is a TOPAS‑Prime with 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. Two product lines of HE‑TOPAS‑Prime are available: a "standard energy" line with input energy of up to 8 mJ @35 fs (up to 20 mJ @100 fs) and HE‑TOPAS‑Prime‑Plus with increased input energy acceptance of up to 18 mJ @ 35 fs (up to 47 mJ @ 100 fs). 60 mJ input energy is possible with longer input pulse of ~150 fs.
Both product lines come with wavelength extension options, which can cover the maximum wavelength range from 189 nm to 20 μm for HE‑TOPAS‑Prime and 240 nm to 20 μm for HE‑TOPAS‑Prime‑Plus.
We also offer a HE‑TOPAS‑800‑ps model for picosecond pump pulses.
