OPO – Optical Parametric Oscillator

Tunable Femtosecond Pulses with GHz Repetition Rate for Ti:Sa Laser

GHz for VIS, NIR, IR

GHz OPO-X by APE is a GHz Optical Parametric Oscillator (OPO) providing tunable femtosecond pulses in the near-infrared (NIR), visible (VIS) as well as infrared (IR) wavelength region.

Ideal for GHz Ti:Sa Laser

It is an ideal choice to add new wavelength ranges to GHz repetition rate Ti:Sapphire lasers, such as taccor tune made by Laser Quantum.

At a Glance

  • GHz repetition rate OPO for Ti:Sa lasers
  • Tunable from < 530 … 740 nm (VIS), 1000 … 1600 nm (NIR) and 1750 … 4100 nm (IR)
  • Completely automated and fully computer controlled
  • TCP/IP remote control with standardized command set for easy programming
  • Integrated high resolution spectrometer and power performance monitoring

Acquisition Software and TCP/IP Standard Software Interface

All models come with an easy to use data acquisition software, allowing for real-time data display. Furthermore, the TCP/IP-based standard software interface by APE makes it straight forward to set up remote control. This allows you, for example, to design your own automated measurement routines. Simply use our protocol templates for rapid configuration with familiar programming languages, including C++, C#, LabVIEW, Python, Matlab, and Ruby.
