TOPAS-PRIME is a collinear femtosecond optical parametric amplifier designed for Ti:Sapphire lasers.

The standard TOPAS-PRIME model accepts pump pulse energy of up to 3.5 mJ @ 35 fs (up to 4 mJ @ 100 fs), while TOPAS-PRIME-PLUS accepts higher pump pulse energy, up to 5 mJ @ 35 – 100 fs. Both models come with wavelength extension options, covering a wavelength range from 189 nm to 20 μm.

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

  • 800 nm wavelength
  • 1 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 output pulse energy scales linearly in 1 – 5 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.
