The Koheras ADJUSTIK is a rack-mountable benchtop single-frequency DFB fiber laser with center wavelengths of 1550.12 nm and 1064.00 nm. This low-noise fiber laser platform features ultra-low phase noise and Hz-range linewidth normally only found in costly scientific systems. It provides output powers ranging from 10 mW up to 2 W depending on the model. The laser is ideal for experimental work for all kinds of low noise applications e.g. for metrology and coherent sensing where laser noise is critical. The company also provide special systems anywhere in the 1535 - 1580 nm and 1030 - 1120 nm ranges.
