Environmental sensing techniques are used to identify the characteristic spectroscopic optical "fingerprint" of an atom or molecule. In fields such as pollution sensing and monitoring or battlefield standoff detection, laser-based techniques are often the solution to monitor trace chemicals at a distance.
CW Single Frequency Sources:
Low-noise, narrow-linewidth, single-frequency, continuous wave (CW) lasers. NP Photonics' single-frequency fiber lasers provide exceptionally low noise performance in both erbium (1.55-micron band) and ytterbium (1.0-micron band) configurations with output power available up to 50W.
Q-Switched & Ultrafast Lasers:
NP Photonics' all-fiber Q-switched and ultrafast lasers are customizable in erbium (1.55-micron band), ytterbium (1.0-micron band), thulium and holmium configurations (2-micron).
