Description

The CW tunable laser and extraordinary Titan is the pioneer commercial fully-automated 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 ( <80 μrad), Titan delivers high CW output power ( >4 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.

The CW tunable laser Titan integrates 4 key modules: 1) the DFB fiber laser and amplifier unit, 2) the DFB fiber laser control unit (integrated on a rack), 3) the OPO optical head (to be located on an optical table), 4) the OPO all-digital control electronics unit (integrated on a rack).

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