Mid infrared semiconductor laser for sensing applications

Abstract

The Mid-Infrared (MIR) Semiconductor Laser is very popular, high in demand and has been developing at a rapid pace during the last few decades due to the importance of their wavelength range in the electromagnetic spectrum. The reason for its popularity is that it can offer a wide range of applications such as photonic sensing for the environment, defense and homeland security, health monitoring: breath analysis and gas sensing applications. The usage of a newly designed compact single mode tunable laser for gas sensing applications will be investigated in this research paper. The purpose is to investigate the many characterizations of mid-infrared lasers used for gas sensing measurements, such as current, voltage, and spectrum characteristics. Make comparisons between existing technologies and the newly developed laser technology at the same time. It is critical that by the end of this study, you have a better understanding of the various types of lasers, their functioning principles, and their applications.
