Product Overview:

639nm, 5mW Fiber Coupled Laser Diode Overview

The LDI-639-FP-5-DIL-SM1 is a single mode Fabry-Perot laser diode coupled to G.657.A1 optical fiber, and packaged into a DIL package with a monitor photodiode. The CW output power is 5mW.

The DIL package includes an integrated monitor photodiode, thermoelectric cooler, and temperature sensor for enhanced thermal stability.

The laser comes standard with FC/APC connector; FC/PC is also normally in-stock. 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.
