Precilaser Thulium fiber sees lasers are single-frequency, DFB fiber laser sources. They deliver true single-mode (TEM00), mode-hop-free, low RIN noise performance with excellent wavelength stability. Their Thulium doped laser operates with a Lorentzian linewidth of <3kHz and with powers ＞10mW@>1695nms and ＞5mW@>2050nm.
The Thulium laser is widely used in quantum computing, for example, 1762nm can be used in quantum computing systems based on Ba+.
A Single-frequency Distributed Feedback (DFB) fiber laser is a fiber laser the seed of which has a fiber cavity comprising a periodic structure that stands as a distributed reflector within the specific spectrum of wavelengths.
The cavity represents a distributed Bragg reflector. It is made up of two fiber Bragg gratings generating a single-longitudinal-mode (SLM) emission. Usually, there is a phase shift evenly distributed from both sides, in the middle.
