Global semiconductor laser market was valued at $ 9.3 billion in 2022 and is likely to reach $ 18.8 billion by 2032, registering a CAGR of 6.9% over the forecast period of 2023-2032.
A semiconductor laser, also known as a diode laser, is a type of laser that utilizes a semiconductor material as its gain medium. It is a compact and efficient device that emits coherent light through the process of stimulated emission. The operation of a semiconductor laser is based on the principle of population inversion, where the majority of electrons are excited to a higher energy level than their natural state. This is achieved by injecting a forward electric current through the semiconductor material, which causes the electrons to move from the lower energy levels to the higher ones.
