High power IR emitter, as the name suggests, refers to a device that emits infrared radiation with high power. In recent years, with the rapid development of infrared technology, high power IR emitters have been widely used in various fields such as military, medical, industrial, and consumer electronics. This article will introduce the industry of high power IR emitter, including its working principle, types, applications, and future development trends.

Working Principle of High Power IR Emitter

High power IR emitter is based on the principle of semiconductor physics. When the semiconductor material is excited by external energy, such as electrical energy, it can emit infrared radiation. The working principle of high power IR emitter can be divided into two types: thermal radiation and stimulated emission.

Thermal radiation is a form of electromagnetic wave emitted by a body with temperature. When the temperature of the semiconductor material reaches a certain level, it will emit infrared radiation through thermal radiation. The power of the emitted infrared radiation is proportional to the temperature of the semiconductor material.

Stimulated emission is a process in which the excited electrons in the semiconductor material are stimulated by photons to emit photons with the same frequency and phase. The high power IR emitter uses the stimulated emission principle to achieve high power output. The key to the stimulated emission is the use of a laser medium, which can enhance the emission of infrared radiation and improve the power of the emitted infrared radiation.
