TOPAS Optical Parametric Amplifier

TOPAS Optical Parametric Amplifiers

The TOPAS family is a range of white-light seeded femtosecond Optical Parametric Amplifiers (OPAs), which can deliver continuous wavelength tunability from 189nm to 20 microns with high efficiency and via computer control. With more than 1300 units installed worldwide, TOPAS has become an OPA market leader, and a standard tool for numerous scientific applications.

The TOPAS OPAs can be pumped by Ti:Sapphire amplifiers (at 800nm) with pulse duration ranging from 20fs to 200fs and pulse energies from 10uJ up to 60mJ. Custom solutions beyond the given specifications are also available.


  • Typical energy conversion into the parametric radiation > 25-30% (signal and idler combined)
  • Tuning range 1160-2600 nm out of a single box (extendable to 189nm -20µm)
  • High output stability throughout the entire tuning range
  • Nearly bandwidth and diffraction limited output
  • Passive carrier envelope phase (CEP) stabilization of the idler (1600-2600nm)
  • Computer controlled operation
  • Custom solutions available



This product could be used for the following applications:

  • Ultrafast amplifier pumping
