Definition of High Power IR Laser Diode

A high power IR laser diode is a semiconductor laser diode that emits infrared light. It is characterized by its high power output, small size, and low cost. The "high power" here refers to the power output of the laser diode, which is generally more than 10W. The "IR" represents the infrared spectrum, which is the light with a wavelength between 700nm and 1mm.

Working Principle of High Power IR Laser Diode

The working principle of a high power IR laser diode is based on the stimulated emission of electrons in a semiconductor material. When a forward bias voltage is applied to the diode, electrons and holes are injected into the active region. Through the interaction of electrons and holes, photons are generated, and the photons are amplified and emitted as laser light after passing through the cavity. The structure of a high power IR laser diode generally includes the following parts: the semiconductor material, the p-n junction, the cladding layer, the mirror, and the package. The semiconductor material is the core of the laser diode, which determines the emission wavelength of the laser. The p-n junction is the active region of the laser diode, where the stimulated emission occurs. The cladding layer is used to confine the laser light in the cavity. The mirror is used to reflect the laser light and form a resonant cavity. The package is used to protect the laser diode and facilitate its application.
