Geographically, North America dominated the laser diode market in 2019, as per the observations of the market research company, PS Intelligence. This is credited to the increasing research and development (RD) activities being conducted in the military and defense sector, growing usage of these diodes in the healthcare sector, and the existence of leading telecommunication companies in the region.

In addition to this, the use of laser diodes in cosmetic surgeries and pigmentation reduction, hair removal, tattoo removal, and body contouring processes is also pushing up their demand in the region. Whereas, the market is predicted to register the fastest growth in the Asia-Pacific (APAC) region in the upcoming years. This is attributed to the mushrooming requirement for laser diodes and various associated laser-based technologies and the ballooning industrialization and manufacturing activities in the region.

Due to the various benefits provided by optical data storage devices such as the adoption of low-power beams for storing and retrieving digital data from several storage devices, they are being increasingly preferred in multiple industries. Hence, with the growing usage of laser diodes in the automotive, healthcare, and military and defense sectors, their sales will boom all over the world in the coming years.
