Distributed Feedback (DFB) Diode Lasers are fixed wavelength single mode diode lasers. Typical geometrical sizes of the laser chip are 1000µm x 500µm x 200µm (length x width x height). The laser chip is grown by MOVPE of compound semiconductor material. The optical gain is provided by double heterostructure which include several Quantum Wells for electronic confinement. Typcal emitter width range between 3µm and 7µm. The single mode emission is enforced by a Bragg grating with the laser chip. The surfaces of the laser chip act as cavity mirrors due to the difference of the refractive index of the laser material and the surrounding air. The rear facet of the laser chip is provided with a high reflection coating. The front facet of the laser chip is provided with a high quality antireflection coating for avoiding the Fabry Perot modes of the laser chip. Distributed Feedback (DFB) Diode Lasers are available at almost any wavelength between 760nm and 2800nm.

Koheras AdjustiK™ and Koheras BoostiK™ Systems are narrow linewidth fiber laser turn-key benchtop systems based on a truly single mode, single frequency DFB (Distributed-Feedback) Fiber Laser with extremely high frequency stability and low phase and intensity noise.
The Koheras AdjustiK™ System is a single stage amplified system with up to 200 mW of output power, whereas the Koheras BoostiK™ System is based on dual stage amplification with up to 2 W of output power.
This range of benchtop laser systems is typically offered as rapidly deployable sources for research laboratories that wish to use it as a tool for scientific work and not spend time on setting up a laser system. The benchtop models are based on the Koheras BasiK™ Module seed technology and are upgradable in terms of output power. The systems are supplied with Koheras GraphiK™ software for the control and read-out of numerous laser parameters on a pc such as wavelength, output power, and RIN suppression.
A part from interferometric sensing and LIDAR, these laser systems are very useful sources for various scientific applications (more information available in the application section)
