Koheras has released the Basik, which is a single frequency, low noise distributed feedback (DFB) fibre laser system in a compact and rugged package with passive vibration isolation.

It is designed for industrial OEM integration into advanced sensor interrogation systems for e.g. oil exploration and submarine detection, as well as other interferometric applications such as perimeter detection. 

The module has been developed as a building block for either single wavelength systems or multi-wavelength DWDM systems with up to 10 different wavelengths. It offers a low phase/frequency and vibration noise and is available with up to 50mW of output power. It is controllable via RS-485 interface and can optionally be provided with Koheras GraphiK software enabling the user to monitor and control multiple laser parameters. Other features include active RIN suppression, thermal tuning, and optionally kHz piezo modulation e.g. for frequency stabilisation. The fibre laser output is terminated with an FC/APC SMF-28 pigtailed connector and can optionally be provided with polarisation maintaining output.
