27 Sep 2007 The new "Redphoton® DFB" and the "Blue and Redphoton® WS" versions. The lasers offer narrow linewidth and high coherence length in the 375nm to 1064nm wavelength region. The "Redphoton® DFB" that is especially characterised as a narrow bandwidth diode laser with less than two megahertz has a high output performance and optimal adjustability. The integrated DFB laser diodes are based on optical Bragg gratings which are integrated into the active region of the semiconductor to be able to achieve a narrow band emission and a high coherency up to a length of 250 metres. The new "Redphoton® DFB" laser module from Omicron that is fibre coupled if necessary is available in a wide range of infrared wave lengths. The "Redphoton® DFB" that can be used as an ideal source of light for applications such as Raman spectroscopy, terahertz generation, alkaline spectroscopy as well as gas detection.
Laser diodes with 375 nm to 980 nm are used in an External-Cavity-configuration with the "Blue and Redphoton® WS" versions to produce narrow banded and wavelength stabilised emissions. The wavelength stabilised WS models of the Photon series are suitable for all UV, VIS and Infrared applications where, for example wavelength sensitive elements such as AO modulators and electro optical deflectors are used in the path of the beam. The ultraviolet, violet and blue "Bluephoton® WS" laser diode modules are the most up-to-date technical sources of light for the modern replacement of gas lasers such as Helium - Cadmium, Argon Ion and Krypton Laser in high end applications such as micro lithography, digital holography, holographic data storage, wafer inspection, Laser-Scanning-Microscopy and many others.
As with all laser diode modules of the Photon series, the "Redphoton® DFB" and "Bluephoton® WS" are also based on the modular principle of Omicron that has an enormous choice of items such as direct fibre coupling, focussing and collimation optics, optical insulators, electro optical monitoring and much more.
