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

Please provide the following information to download the White Paper.


Improve Laser Diode Lifetime: Over the years, laser diode development has led to increased output power, which is excellent for many applications, except you are now contending with added waste heat. The mounting or heatsinking of the laser package is of tremendous importance because operating temperature strongly influences laser lifetime and performance. Effectively achieving correct mounting or heatsinking of the laser package 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. Ensuring the laser diode is mounted correctly will provide the best performance and most extended lifetimes.

Laser diode is a generic term that includes several different semiconductor lasers and many additional types of housings or packages for these semiconductor lasers. The more common types of semiconductor lasers include:

  • Fabry-Perot Laser Diodes
  • Stabilized Laser Diodes
  • Vertical-Cavity Surface Emitting Lasers (VCSEL)
  • Quantum Cascade and Interband Cascade Lasers

There are many different laser diode packages. We try to supply enough general advice and precautions so that regardless of the laser diode package you have, you will have a basic understanding of the requirements needed to properly mount the laser for optimum lifetimes and performance.
