SINGLE-FREQUENCY LASER For 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. All laser parameters can be set and monitored using a PC and an RS-232 interface. Standard wavelengths are 760, 763, 773, 780 and 785 nm, with others available upon request. Single-mode fiber coupling also is available.
