TEC-100 / TEC-120 Littrow Laser System - Lynx

Sacher Lasertechnik improved the extended cavity concept by avoiding all compromises. The external cavity is realized with class D anti-reflection coated diode lasers and with a high efficiency diffraction grating. This results in the best performance for an external cavity diode laser system in the Littrow configuration. An increase of the output power and the total performance of the Littrow cavity is achieved by outcoupling the light of the rear facet of the laser diode. Typical power values range between 20mW and 200mW for single mode diode laser, depending on the wavelength. 

 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.
