Request InfoToptica Photonics AGFor use in Raman applications, gas sensing, interferometry, holography and drug screening, Toptica Photonics AG has unveiled the single-frequency dfBeam diode laser. It combines features of the iBeam series with those of distributed feedback laser diodes. It offers a linewidth of <0.001 cm–1, a coherence length of >2.5 m, diffraction-limited TEM00 beam quality, a circular beam shape and a 156 × 56 × 66-mm3 footprint. The company says that coherence properties are maintained even under harsh conditions, and that mode competition and mode hops are eliminated.
