Diode laser is an electronic device that utilizes a PN junction with binary or ternary semiconductor materials. When a voltage is applied externally, electrons transition from the conduction band to the valence band and release energy, thereby producing photons. When these photons repeatedly reflect in the PN junction, they will burst out a strong laser beam. Semiconductor lasers have the characteristics of miniaturization and high reliability, and their laser frequency can be adjusted by changing the material composition, PN junction size, and control voltage.
Diode lasers are widely used in fields such as fiber optic communication, optical discs, laser printers, laser scanners, laser indicators (laser pens), etc. They are the largest laser in terms of production volume. In addition, semiconductor lasers have extensive applications in laser ranging, LiDAR, laser communication, laser simulation weapons, laser warning, laser guidance and tracking, ignition and detonation, automatic control, detection instruments, etc., forming a broad market.
