Ứng dụng của laser yttrium aluminium garnet trong ngành công nghiệp hiện đại
Yttrium aluminium garnet (YAG) lasers have emerged as indispensable tools in modern industries, revolutionizing various sectors with their remarkable capabilities.
What is yttrium aluminium garnet laser?
Yttrium aluminium garnet (YAG) laser is a type of solid-state laser that uses a crystal of yttrium aluminium garnet doped with neodymium, ytterbium, or erbium as the gain medium. YAG lasers are known for their high power, efficiency, and versatility, making them suitable for a wide range of applications in various industries.
How does a YAG laser work?
A YAG laser works based on the principle of stimulated emission. The YAG crystal is pumped with energy, typically from a flash lamp or a diode laser, exciting the atoms within the crystal to higher energy levels. When these excited atoms return to their ground state, they emit photons of light. The emitted photons are then amplified through a process called stimulated emission, resulting in a highly focused and coherent beam of laser light.
Why are YAG lasers used in laser cutting?
YAG lasers are widely used in laser cutting due to their high precision, speed, and ability to cut through a variety of materials with minimal heat-affected zones. The highly focused laser beam can create intricate cuts with high accuracy, making them suitable for applications requiring tight tolerances.
The versatility, precision, and efficiency of YAG lasers have solidified their position as essential tools in modern industries. From material processing to medical applications, YAG lasers continue to drive innovation and enhance productivity across various sectors.
