Koheras ADJUSTIK – single-frequency lasers
The Koheras ADJUSTIK is a rack-mountable benchtop single-frequency DFB fiber laser. We have based the ADJUSTIK on our renowned BASIK laser modules. Get a low phase noise and a Hz-range linewidth typically only found in costly scientific systems.
Our standard systems are available at 1550.12 nm and 1064.00 nm. Or you can get any other wavelength in the 1535–1580 nm and 1030–1120 nm ranges.
Ideal for low-noise applications
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 user-friendly CONTROL software for the control and read-out of laser parameters on a PC such as wavelength, output power, and RIN suppression.
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.
Want more details?
If you want more details about phase noise, spectral linewidth, frequency stability, or how to wavelength tune your Koheras laser, we have some application notes for you.
Laser phase noise is a frequency-domain view of the noise spectrum around the laser signal. Read more about phase noise in single-frequency lasers.
Spectral linewidth is a measure of the spectral content of the laser light. Read more about linewidth measurement methods.
The laser’s frequency stability is often described in terms of its spectral linewidth. However, this term lacks detail about the laser frequency noise which is often critical in laser applications. Read the analysis of the laser frequency stability using beat-note measurement.
The wavelength of the laser is controlled by the temperature and strain of the DFB cavity. Learn how to tune your Koheras laser.
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.
