TOPAS TRAVELING-WAVE OPTICAL PARAMETRIC AMPLIFIER OF SUPERFLUORESCENCE
PURPOSE
Source of widely tunable femto/picosecond pulses.

APPLICATION
Research in nonlinear optics, time resolved spectroscopy.

COMPOSITION
TOPAS consists of an independently pumped superfluorescence generator, two preamplifiers, and power amplifier. All these stages are geometrically arranged using a single nonlinear crystal.
The seed signal is produced in low-energy preamplifiers, that are optimized for the best spectral and spatial filtering properties. The power amplifier uses <95% of the pump energy and is adjusted for high conversion efficiency along with the beam quality and duration of the converted pulses. TOPAS can be adopted to be driven by a variety of laser systems, with pulsewidths ranging from 25 fs to 50 ps.

FEATURES
  • Travelling wave single crystal, four amplification stage configuration
  • Energy conversion into the parametric radiation up to 35%
  • Nearly bandwidth and diffraction limited output
  • Upgradability for pump energy, wavelength and pulsewidth extension
  • Computer controlled operation
  • Optional frequency mixers
