Diode Laser A diode laser is a type of laser commonly used in laser engraving machines due to its compact size, efficiency, and affordability. Diode lasers emit coherent light through the stimulated emission of photons in a semiconductor material. In laser engraving, diode lasers offer precise control over engraving parameters and are suitable for a wide range of materials, including wood, acrylic, and certain metals. Diode lasers are preferred in laser engraving for their reliability and low maintenance requirements, making them suitable for both hobbyist and industrial applications. |
