How to Improve Laser Diode Lifetime! Advice and Precautions on Mounting

Laser diodes have increased in output power and the increased power means added waste heat to contend with. The mounting or heatsinking of the laser package is of tremendous importance because operating temperature has a strong influence on laser lifetime and performance. Achieving correct mounting or heatsinking of the laser package effectively is not as simple as many would assume. This article will discuss the various package types and the best practices for ensuring the laser diode is mounted correctly. Making sure the laser diode is mounted correctly will ensure the best performance and longest … Read More

Choosing the Right Connector for Your Fiber-Coupled Laser Diode

Having trouble deciding which fiber-coupling connection is best for you? In this paper, we review pros and cons of the most common fiber optic connectors and the two main connector styles – FC and SMA, the importance of the self-centering ferrule and physical contact and polishing angle in regard to coupling efficiency and back reflections. After reading this white paper, you will come away with an in-depth understanding of the optomechanical structure of fiber optic connectors, their variants and tolerances, and which of these will better suit y… Read More

Quantum Cascade Lasers (QCLs) for Infrared Countermeasures

After reading this white paper, you will come away with an understanding of how heat-seeking missiles function and why infrared sources are necessary for protecting military aircraft from attack. This article also explains the basic functionality of QCLs, pointing out both the similarities and differences between QCLs and classical semiconductor lasers. Finally, we discuss the specific laser requirements needed to be effective at disorienting a heat-seeking missile, and why the PowerMir series of QCLs from mirSense are ideal for this ap… Read More
