Arktis Laser a wide array of single frequency/single longitudinal mode lasers with narrow linewidth 10-6 nm and long coherence length (>100 m). In addition to the narrow linewidth and long coherence length, frequency stabilized SLM lasers have the advantage of having a stable frequency and low frequency noise. These lasers are commonly used in applications such as Holography, Raman Spectroscopy, Precision measurement, Interference lithography, Biomedical/fluorescence, Microscopy, Atomic excitation/absorption, and more.
