TOPAS™ Automated Ultrafast OPA
TOPAS™ Automated Ultrafast OPA

The TOPAS Advantage
    • Tunable from 1150–2600 nm
  • Optional harmonic and frequency-mixing accessories extend tuning range from 189 nm to 20 mm
  • Pumped with Spitfire Pro (<35 fs, <40 fs and <120 fs) with up to 3 mJ for highest output power
  • Computer controlled
  • Full-automation option
  • White light seed for enhanced output stability
  • Multiple TOPAS can be pumped by a single Spitfire Pro amplifier
  • WinTOPAS software can control up to four TOPAS OPAs

Product Detail

The TOPAS™ is a kilohertz ultrafast optical parametric amplifier (OPA). It broadens the wavelength coverage of the Spectra-Physics Spitfire® Pro amplifiers and provides gap free tunability from deep UV to mid-IR. Featuring a complete set of wavelength extension options, the TOPAS allows tuning from 189 nm to 20 mm.



The Spitfire Pro – with its high output energy (up to 3mJ per pulse at 1 kHz), ultrashort pulse duration (as low as 35 fs) and exceptional output quality and stability – is the ideal pump for the TOPAS. These superior output characteristics ensure maximum conversion efficiency for the parametric amplification process, thus producing high energy, near-transform-limited pulses throughout the tuning range.

Applications
    • Ultrafast, time-resolved spectroscopy
  • Multicolor pump-probe studies
  • Transient absorption spectroscopy when used with Newport Helios spectrometer
  • Nonlinear optics
