Habilitación de láseres de nanosegundo RFH de 'carbono dual' para grabado en piedra

La piedra es un material muy utilizado con una doble función constructiva y decorativa. Para maximizar el valor comercial del desarrollo de la piedra, ahora los comerciantes también grabarán texto, patrones, etc. en la piedra de acuerdo con las necesidades de los consumidores para aumentar el valor agregado del producto.

El proceso tradicional de tallado en piedra ya no puede satisfacer la búsqueda de belleza tallada de los consumidores actuales. Por ejemplo, los métodos tradicionales de esmerilado, arenado, tallado, etc. tienen muchas desventajas. El patrón y el texto no son consistentes, y los bordes no son delicados ni suaves, dando a las personas una sensación áspera. Para algunas piedras con alta dureza, el proceso tradicional es propenso a grietas durante el procesamiento, lo que resulta en desechos del producto. Además, desde la perspectiva de la protección del medio ambiente, estos procesos son propensos a producir residuos, polvo y aguas residuales, y tienen desventajas como un alto consumo de energía y una alta contaminación.

With the rapid development of laser technology, the application industry of laser has become more and more extensive. With the continuous exploration of laser application in the stone processing industry, now stone carving can also be processed by laser. RFH nanosecond solid-state laser, narrow linewidth, high peak power and other characteristics, "match" the needs of the stone processing industry.

Since the hardness of the stone varies according to the specific material, in order to carve a certain depth of marks on the surface of the stone, the laser needs to have a very high peak power, so that the laser beam can damage the surface of the material when it touches the surface of the stone. chemical bonds, which in turn vaporize instantaneously, leaving "engraved" traces.

The average output power of the nanosecond solid-state laser is more than 5W, and the output wavelength is 355nm. It is a cold light source and can be well absorbed by the material. The pulse width is less than 20ns, the heat-affected zone is small, and micro-cracks are not easily generated during engraving. The beam quality is excellent (M2<1.2). With accessories such as field lenses, micron-level light spots can be obtained. The peak power is high, and the engraving accuracy and depth are high. foot, and does not produce dust.

In view of the harsh environment of stone processing, the nanosecond solid-state laser has taken environmental factors into consideration from the beginning of its design, and the unique resonator design ensures the stability under high power and high repetition frequency. The uniquely designed high-precision electric control platform obtains a high-quality beam through a transmissive spatial filter module while maintaining high pulse stability. These designs enable this laser to meet industrialized 7*24 applications, improving quality and efficiency for users.
