TEC-300 Power Littrow Series - Tiger
Sacher Lasertechnik realized an external cavity diode laser basing on tapered lasers. The laser system bases on more than 10 years of experience in manufacturing external cavity laser diodes. The external cavity is realized with class D anti-reflection coated tapered diode lasers and with a high efficiency diffraction grating. The output power is coupled out via the rear facet. This results in the best performance for an external cavity diode laser system in Littrow configuration. Typical power values range between 500mW and 1000mW, depending on the wavelength. This laser designs available by model TEC-300.
Below is a simplified drawing of the configuration

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. Optical isolators and angled fiber connectors (FC/APC couplers) are available upon request.
