TEC 500 Layout TEC 520 Layout


Sacher Lasertechnik has realized the synchronization between grating defined and cavity defined wavelength by only a simple rotation of the mirror. The adjustment of the pivot point is done during the wavelength scanning operation of our Littman/Metcalf laser system, according to our patent no. 5,867.512. Due to this special method, we are able to ensure the best mode-hop free tuning behavior. An increase of the total perfomance of the Littman/Metcalf laser is achieved by using a high efficiency grating and outcoupling the light of the rear facet of the laser diode. With this approach, we are able to increase the output power to more than 100mW.

Below are simplified drawings of the configurations

Single-mode fiber coupling option

Due to the excellent mechanical stability of our Littrow laser system we are able to perform high efficiency fiber coupling with coupling efficiencies between 40% and 70% into single mode polarization maintaining optical fibers.
