Koheras BASIK MIKRO compact low noise single-frequency OEM lasers
The Koheras BASIK MIKRO is the smallest industrial single frequency fiber laser on the market and it is designed for OEM integration in industrial sensing systems. The module includes fully integrated laser control electronics, as well as continuous monitoring of the laser performance. Based on a truly single mode DFB fiber laser architecture, it offers ultra stable performance free of mode-hops.
The module is available in two different laser versions, C15 and E15. The standard wavelength is 1550 nm and the MIKRO is available with output wavelength anywhere in the 1535 to 1580 nm range. Moreover, the laser offers a wide thermal wavelength tuning range and can be combined with fast wavelength modulation e.g. for external stabilization.
The lasers are available with PM (Polarisation Maintaining) or non-PM output.
For easy control, the MIKRO is available with an optional USB interface kit and can be controlled via NKTP CONTROL graphical user interface.
