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 our NKTP CONTROL graphical user interface.
