Koheras has released the third generation BasiK Module featuring improved vibration sensitivity, all digital control, selective current/power operation mode, increased output power, reduced size, weight and power consumption.
The BasiK Module is designed for OEM integration into advanced sensor interrogation systems for oil exploration, submarine detection, perimeter detection and other interferometric applications that require high frequency stability and low noise laser operation.
The module is also ideal as a seed laser for amplified systems, e.g. for atomic trapping and other scientific applications. It is a single frequency, low noise Distributed Feedback (DFB) fibre laser system. Its monolithic, rugged package is 40 per cent smaller and lighter than the previous version, with a passive vibration isolation improved by -10dB. With its versatile and flexible building block design, the new BasiK Module can be provided either as single wavelength systems or grouped for multi-wavelength DWDM systems.
The new BasiK Module is offered at custom specified wavelengths within the C- and L-band as well as within 1.03–1.12µm now featuring up to 50mW of optical output, powered by +12 VDC single supply. Furthermore, its power consumption has been reduced by 20 per cent. The laser is thermally, linearly tunable over a range of up to 800pm in modehop-free operation, and optionally with fast piezo tuning at kHz modulation bandwidth.
For the first time, the BasiK Module features an intelligent, flexible, all digital interface with RS-485/USB 2.0 connector, to monitor and control all laser parameters via the user's own microprocessor platform or via the new Koheras GraphiK software.
