Koheras ADJUSTIK Single-Frequency Lasers

The Koheras ADJUSTIK is a rack-mountable benchtop single-frequency DFB fiber laser. Based on our renowned BASIK modules, the ADJUSTIK is the pinnacle of industrial low noise lasers featuring ultra-low phase noise and Hz-range linewidth normally only found in costly scientific systems.

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 our Koheras BASIK Module seed technology and are upgradable in terms of output power. The systems are supplied with our NKTP CONTROL software for the control and read-out of laser parameters on a PC such as a wavelength, output power, and RIN suppression.

IDEAL FOR LOW-NOISE APPLICATIONS

The ADJUSTIK lasers are ideal for experimental work for all kinds of low noise applications e.g. for metrology and coherent sensing where laser noise is critical.

1) Lorentzian.
2) Relative to the center wavelength at room temperature. If the laser case temperature is outside the interval of approx. 10-50°C, the range of detuning from the center wavelength may be reduced.
3) Modulation depth and frequency are typically slew-rate limited, depending on the power.
