TOPAS-HR is a high repetition rate optical parametric amplifier for applications requiring 10 kHz – 1 MHz repetition rate. It provides high output stability, high output pulse and beam quality, full automation and optional frequency mixing stages to extend the tuning range.

TOPAS-HR can be pumped by high repetition rate femtosecond Ti:Sapphire lasers and is an invaluable tool for ultrafast spectroscopy, nonlinear microscopy, microstructuring, and other applications.
