The extraordinary Titan is the pioneer commercial mid-infrared continuous-wave optical parametric oscillator (CW OPO). Introduced to the market in 2018, Titan delivers continuously tunable output wavelengths in the mid-IR, across 1435 – 4138 nm (6969-2416 cm-1)*. The full spectral range is achieved with a single set of optics without the need to exchange any module.

Radiantis´ unique expertise in frequency converted lasers has enabled the exceptional design of the Titan OPO family. As a sealed and fully-automated system, with excellent TEM00 beam quality (M2 < 1.3) and beam pointing stability ( <40 μrad), Titan delivers high CW output power ( >3 W at the peak of the tuning range) with a linewidth <100 MHz in the signal range.

Hands-free operation is ensured thanks to the all-digital control electronics and user control software which can be accessed through the PC GUI interface installed on a dedicated laptop delivered with the OPO. Titan can also be controlled via remote commands.

Titan integrates 4 key modules: 1) a rack DFB fiber laser and amplifier unit, 2) the OPO optical head, 3) a rack OPO all-digital control electronics and 4) a rack compact water-cooler. The fiber laser, the OPO control electronics and the water cooler are rackable  The OPO optical head needs to be positioned on an optical table to reduce vibrations and ensure maximum stability.

The broad wavelength range, narrow linewidth, and fully-automated tunability across the mid-IR enables cutting-edge research in diverse areas such as spectroscopy and microscopy for biotechnology, fundamental physics and chemistry, as well as material characterisation, device calibration and quantum technologies.

Several Titan models are available which provide different characteristics of average output power and wavelength coverage, as detailed in the specification table below.
