Product Overview:

850nm, 50mW Fiber Coupled Laser Diode Overview

The model LDI-850-FP-50-Butterfly is an AlGaAs quantum well laser diode coupled to PM optical fiber. It is offered in a 14-pin Butterfly package with internal monitor photodiode, TE cooler and temperature sensor. The CW output power is 50mW, pulse power output is 100mW. The 14-pin Butterfly package includes an integrated photodiode, thermoelectric cooler, and temperature sensor for enhanced thermal stability. These 850nm laser diodes ship with an FC/APC fiber connector but can be ordered with other connectors; please contact us for information on fiber connector options.

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.
