Description

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 @ 20 – 70 fs (up to 4 mJ @ 70 – 200 fs), while TOPAS-PRIME-PLUS accepts higher pump pulse energy, up to 6 mJ @ 70 – 200 fs. Both models come with wavelength extension options, covering a wavelength range from 189 nm to 20 μm.

Specifications Notes

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.

CEP STABILIZATION OF IDLER

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.
