Product Overview:

520nm, 20mW Fiber Coupled Laser Diode Overview

The LDS-520-FP-20-COAX is a Fabry-Perot laser diode coupled to Nufern S405-XP optical fiber, and packaged into a hermetic fiber coupled coaxial package. The CW output power is 20mW.

The coaxial package is installed into a double-sided heat sink and mounting bracket for simple handling and mounting as well as enhanced thermal stability.

The laser comes standard with FC/UPC connector; FC/APC is also normally in-stock. Please refer to the data sheet or contact us for information on fiber and 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.
