Harmony: Optical Parametric Amplifier
Find harmony in four perfectly synchronized and precisely tunable wavelength outputs produced by Fluence Harmony Optical Parametric Amplifier (OPA).
Fluence Harmony is a device that precisely converts ultrafast pulses of one band (e.g. 1030 nm pulses coming from Fluence Jasper) into a set of pulsed laser beams tunable in an extremely broad spectrum of wavelengths, ranging from 210 nm to over 10 000 nm. It is equipped with an integrated mini spectrometer and can be automatically tuned with the base wavelength range of 630 up to 2600 nm with intuitive user-friendly PC software.
The growing number of ultrafast spectroscopy techniques has prompted the need for a robust and reliable, self-diagnostic device like Harmony. The Optical Parametric Amplifier can be fully compatible with most femtosecond lasers and provides automated tuning across the basic tuning range.
