OZ Optics produces the Highly Stable Laser Diode Sources (HIFOSS) in a variety of wavelengths. The HIFOSS has a built-in thermoelectric (TE) cooler to maintain the laser diode at a stable temperature and an isolator to reduce effects of backreflection. This substantially increases the stability of the source.
Both the receptacle-style source and the pigtail-style source offer the choice of polarization maintaining, singlemode, or multimode fiber output, with a wide range of receptacles or connectors. OZ Optics recommends angled connectors for optimum stability.
Model Number: HIFOSS-11-9/125-1550-P-1.5-3U-1-ISOL
It has an FC interface.
