The Semiconductor Laser Market size is estimated at USD 8.24 billion in 2024, and is expected to reach USD 15.45 billion by 2029, growing at a CAGR of 13.40% during the forecast period (2024-2029).
A semiconductor laser, also known as a laser diode and diode laser, is a type of laser that utilizes a semiconductor material as its active medium. It is a subset of the larger classification of semiconductor pn junction diodes. Semiconductor lasers are typically small, often about the size of a grain of salt. They are solid-state lasers based on semiconductor gain media, where optical amplification is achieved through stimulated emission at an interband transition under conditions of high carrier density in the conduction band.
The working principle of a semiconductor laser involves the injection of charge carriers (electrons and holes) into a pn junction formed within the semiconductor material. When a forward electrical bias is applied across the laser diode, charge carriers are injected from opposite sides of the pn junction into the depletion region. This injection of charge carriers creates a population inversion, where more electrons occupy the higher energy levels than the lower energy levels. When the electrons in the conduction band recombine with holes in the valence band, they emit photons through stimulated emission, resulting in the generation of laser light.
The Semiconductor Laser market is highly fragmented, with the presence of major players like Coherent Corporation, Sharp Corporation, Nichia Corporation, IPG Photonics Corporation, and TT Electronics. Players in the market are adopting strategies such as partnerships and acquisitions to enhance their product offerings and gain sustainable competitive advantage.
