Types of Infrared Wave Sources

Infrared wave sources can be divided into two main categories: solid-state infrared wave sources and optical infrared wave sources.

1. Solid-state infrared wave sources

Solid-state infrared wave sources mainly include semiconductor lasers, diode lasers, and quantum dots. These devices emit infrared waves through the stimulation of electrons in a semiconductor material. They have the advantages of small size, low power consumption, and long service life. Semiconductor lasers are widely used in optical communication, fiber optic communication, and medical equipment. Diode lasers are commonly used in laser marking, laser cutting, and laser welding. Quantum dots have excellent infrared emission properties and are promising in the field of infrared photodetectors.

2. Optical infrared wave sources

Optical infrared wave sources mainly include light-emitting diodes (LEDs), incandescent lamps, and gas discharge lamps. These devices emit infrared waves by converting electrical energy into light energy. Among them, LEDs have the advantages of high efficiency, long life, and low cost, and are widely used in infrared remote control, infrared imaging, and infrared communication. Incandescent lamps are commonly used in infrared heating and infrared night vision devices. Gas discharge lamps have high power output and are suitable for high-power infrared applications such as infrared welding and infrared curing.
