Diode Laser:
A diode laser, or semiconductor laser, uses a tiny piece of semiconductor material as its core. When electricity is applied to this material, it causes electrons to move and release energy as light. This light, usually in the visible or near-infrared spectrum, is then amplified to produce a concentrated laser beam.
Diode lasers are precise and often used for marking plastics, metals, and ceramics due to their accuracy in detailed tasks. They are compact, efficient, and easy to use in smaller spaces.
