OPO-X

Tunable OPO For Ti:Sa Lasers■■ OPO-X, a synchronously pumped Optical Parametric Oscillator (OPO), is ideal for wavelength extension ofmodelocked fs or ps Ti:Sapphire lasers.

■■ It is suitable for both femtosecond and picosecond Ti:Sa lasers. The wavelength range covers thespectrum from 505 ... 4000 nm.

Wavelength extension for Ti:Sa lasere.g. for Mira (HP), Chameleon Ultra II and Vision II, Tsunami, MaiTai, etc.
Independent Pump- and Signal tuning
Fully automated tuning
Windows-based control software included
Jitter-free generation of pulses

1Customization
OPO-X can be provided with several options and modifications:
Output of Idler beam (in addition to output of Signal beam)
Depleted pump output (not in combination with Idler)
Customized wavelength ranges
Adaptation to various pump laser cavity lengths and pump pulse width
Difference Frequency Generation device for MIR generation up to 11 µm
Simultaneous access to IR and VIS output, and Idler

Maximum Flexibility■■ OPO-X is based on a FAN crystal architecture. Great flexibility is given because the OPO wavelength canbe set independently of the pump wavelength. Any wavelengths between 740 nm and 880 nm are suitablefor pumping.

Femto- or Picosecond Operation■■ All OPO-X systems can be operated in both femtosecond and picosecond mode, depending on thecorresponding pump laser. Optic components are available for this purpose, which can be easily
exchanged by the user.

Automated Tuning■■ The actual Signal wavelength and bandwidth is measured by an internal high-resolution spectrometer,

and the power by calibrated photodiodes.

■■ The OPO-X is also equipped with diagnostics for the Pump wavelength, power and repetition rate. Thewavelength tuning is done by simply entering the desired wavelength into the OPO control software.

■■ Even a change in the pump wavelength is detected and the OPO-X adapts automatically. The OPO-X iscompletely controllable via PC.
