Product Overview:

670nm, 5mW Laser Diode, PM Fiber-Coupled

This Fabry-Perot laser is offered in a polarization-maintaining fiber-coupled coaxial package, with integrated photodiode. This laser is coupled to 4 μm fiber, NA 0.12, and terminated with an FC/PC connector. Other options are available; inquire for options and details.

These high stability fiber coupled laser diodes are designed and manufactured to meet the most demanding R&D and industrial applications. Proprietary design, packaging, and fiber coupling processes produce laser diodes with very high stability and low noise. Each laser diode is subject to extensive testing and burn-in before shipment to ensure the highest possible levels of quality and long term reliability.

Proper Handling and Operation of Diode Lasers

Diode lasers are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
