Product Overview:

660nm, 20mW Fiber Coupled Laser Diode Overview

The LDI-660-FP-20 is an InGaAlP quantum well laser diode coupled to a single-mode optical fiber and packaged into a hermetic TO-case, with a monitor photodiode. This compact coaxial laser is mounted in a double-sided bracket to facilitate mounting and heat-sinking.

The laser comes standard with FC/UPC connector, but can be ordered with an FC/APC connector; 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.
