fs / ps MHz OPO | Ti:Sa laser pumped



The OPO PP Auto FAN is a synchronously pumped optical parametric oscillator (OPO) designed to be pumped by a mode-locked ps or fs Ti:Sapphire laser. The OPO crystal is based on a periodically poled (PP) crystal with a FAN structure, which enables a large tuning range from a single crystal as well as a high conversion efficiency and low pump threshold.

Because of the FAN structure the Signal wavelength can be tuned independently of the pump wave- length in the range of the pump wavelength from 740 … 880 nm. This enables a maximum flexibility of simultaneous available wavelengths for the experiment as well as no need for changing of crystals to access the full tuning range from 1000 ... 1600 nm. Optionally, an Idler beam is available covering the wavelengths from 1750 ... 4000 nm.

The OPO is equipped with an internal spectrometer for active wavelength control and stabilization; also sensors for humidity and relative power are integrated. Optionally, an autocorrelator driven by the OPO control unit is available.
All versions of the OPO system can be operated in both femto- and picosecond mode, depending on pump pulse duration by simply exchanging the OPO crystal.
