TOPO
Tunable mid-IR laser for important molecular regions
Absorption spectroscopy is used for gas sensing to monitor the environment, and it is used as a diagnostic tool for combustion and air flow to improve the efficiency of electricity generation and combustion engines. It is used in label-free microscopy for biomedical imaging and semiconductor inspection with the aim to improve human health and technology. The TOPO is also used to develop chip-based sensors that rely on mid-infrared light, and for quantum communications networks that improve data security.
Your Benefits
Wide infrared tuning with high resolution
The TOPO can tune over critical molecular absorption features between 2500 - 4500 cm-1 (2.2 - 4.0 µm) in very small steps (10-4 cm-1 / < 10 MHz) and with narrow spectral linewidth (< MHz).
High power at hard-to-reach infrared wavelengths
The TOPO relies on robust near-infrared lasers and optical nonlinearity to generate Watt-level power at otherwise hard-to-reach wavelengths.
Spectroscopy-ready
The TOPO is turn-key, and all tuning actuators can be remote controlled by the system controller or software for easy and algorithmic tuning.
Options
Narrow linewidth
The standard TOPO has an idler linewidth of 2 MHz (5 ms). With this option, the idler linewidth is reduced to < 100 kHz (5 ms).
Wavelength meter
Combination with suitable HighFinesse wavemeter for specific setups on request.
Locking electronics
A broad variety of electronic locking modules is available for frequency stabilization.
