• Quick and precise, all-automated tuning
  • Passive and stable
  • User-friendly software
  • Perfect extension for the Fluence Jasper laser

Harmony is a compact optical parametric amplifier that converts ultrafast pulses from Ytterbium-based lasers into broadly tunable pulses with wavelengths ranging from 210 to over 10 000 nm. It is equipped with an integrated mini spectrometer and can be automatically tuned in the base wavelength range of 315 up to 2600 nm with intuitive user-friendly PC software. Harmony can be compatible with all Ytterbium-based femtosecond lasers, but it works best with Jasper family femtosecond fiber lasers featuring an exceptional lifetime and beam pointing stability. Being pumped with Fluence Jasper X0 or Jasper Flex series, it can operate at repetition rates ranging from single pulse up to 300 kHz and pump pulse energy from 30 μJ to 200 μJ.
