OPOPO pump tuned

An optical parametric oscillator (OPO) is a laser source which splits a pump photon into two photons with longer wavelengths (Signal and Idler). Optionally, the Signal wavelength can be intra cavity frequency doubled.

The APE OPO is a synchronously pumped OPO with a mode-locked Ti: Sapphire laser as pump source. The OPO is designed for highly efficient wavelength conversion and it covers a wavelength range spanning from the visible to the mid infrared. Depending on the pulse width of the input pulses, it can be operated in fs or ps mode. Since the conversion process from the pump wavelength to the Signal and Idler is jitter free, the OPO is the ideal light source for two color experiments such as pump-probe measurements.

Features
  • Very low threshold (< 0.5 W1))
  • High converson efficiency
  • Wavelength independent pulse width
  • Easy to install and user friendly operation
  • Active cavity length stabilization
  • Jitter free generation of synchronized pulses (pump-Signal-Idler)
