TEC-320 Power Littman/Metcalf Series - Tiger
We have designed our TEC 320 Littman/Metcalf Laser according to our patented design, US-Patent no. 5,867,512, further patents pending. The laser system consists of a diode laser, collimating optics, a diffraction grating and a tuning prism. The laser light is collimated and coupled to the diffraction grating. The first order diffraction beam is coupled to a reflection prism which makes our cavity design self-aligning. The reflecting prism feeds the laser beam back to the diffraction grating where it is finally directed back into the laser chip. The rear facet beam of the laser chip is coupled out of the laser system. The major advantages of this laser design are the large mode-hop free tuning range due to the double passing of the diffraction grating and the absolute beam direction stability, and the high output power.
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.
