Why are Semiconductor Lasers Gaining Traction?

The emergence of semiconductor lasers offers an advanced and affordable solution to processes relying on advanced laser applications. 

FREMONT, CA: A semiconductor laser is rapidly becoming one of the most widely utilized laser systems. A semiconductor laser’s structure can be understood via a three-tier breakdown. The medium portion is the junction of the forward-biased P-N diode, which is placed between two metal contacts. A minimum current density is needed for laser production. The laser output becomes active once the minimum current density is reached. 

The main reason behind the popularity of semiconductor lasers is the fact that they produce light with an efficiency that surpasses almost every other laser system. Moreover, laser diodes have long operating lifetimes. Laser diodes are also easy to operate as compared to other laser systems. While these factors contribute to the popularity of semiconductor lasers, here are some of their other major advantages and applications.

Semiconductor laser or diode laser has a fairly simplistic construction as compared to other lasers. Its small size adds to the convenience and ease of usability. The process inside the p-n junction is also extremely efficient due to which there is a low power requirement for diodes. Optical communication is increasingly gaining traction in the modern world. Laser diodes operating in the near-infrared are ideal signal beams for optical data transmission due to their coherent output. This property of a diode laser also makes it extremely efficient in single-mode fibers for large transmission distances. 

Spectroscopy and medicine are two other segments where diode laser can add value. Diode lasers are becoming extremely common in spectroscopy due to their higher power capabilities, narrow bandwidth, and ease of operations. Diode laser also contributes to a wide range of medical applications due to their reliability, brightness, and compact size. For instance, Photodynamic therapy (PDT) and non-invasive surgical procedures are benefitting from the incorporation of semiconductor lasers.

The above advantages of semiconductor lasers are making it the first choice for various industries and verticals.
