Our optical parametric oscillators are the most advanced in the industry, with leading technology plus a range of options to suit every system and customer need.

fs / ps MHz OPO | Ti:Sa laser pumped


The OPO-X is a synchronously pumped widely tunable optical parametric oscillator (OPO) for fs and ps Ti:Sapphire laser pumping, covering the wavelength range from 505 … 4000 nm. It is fully automated, i.e. software controlled tuning over the full specified wavelength range. This is made possible by its new control electronics, internal diagnostics, and Control Software packaged conveniently in a new housing.

The Control Software is equipped with a Software Interface (using TCP/IP). The OPO-X can easily be integrated into larger experimental setups and software controlled environments.

Improved customer support is enabled through internal error diagnosis and extensive log files remotely accessible via TCP/IP interface and LAN, which also enables remote service capabilities.

The OPO-X is based on a FAN crystal, which enables a large flexibility. The OPO wavelength can be tuned independently of the pump wavelength, accepting to be pumped from 740 … 880 nm. This enables a maximum flexibility of simultaneous available wavelengths for the experiment.

All versions of the OPO-X system can be operated in both femto- and picosecond mode (depending on the pump), by simple exchanging a few optical elements.

The new OPO-X is based on A·P·E’s long standing experience in developing and manufacturing fully automated OPOs, such as the Chameleon Compact OPO, or the picoEmerald™.
