激光器出现不久,在材料加工方面便获得了应用。经使用证明,激光加工同以往的任何机械加工方法比较起来,它的加工速度快,质量好,而且还能加工某些用机械加工法不能加工的工件,尤其特殊的是在精密微型加工方面。激光加工主要包括打孔、焊接、切割、划线以及微调、蒸发、破碎和局部热处理等。它的应用面已涉及到各个科学技术领域,特别是对电子工业、精密仪表、航空及机械工业等起着促进作用。近二三年来,激光加工技术进展迅速,在若干工业领域中已达到实际应用水平。主要原因之一,就是固体激光加工设备的价格有了下降,可靠性、稳定性、可调谐性和重现性等大
Shortly after the laser appeared, it was applied in material processing. Proved by the use of laser machining compared with any of the previous machining methods, its processing speed, good quality, but also to process some of the machining can not be machined parts, especially in precision micro-machining. Laser processing, including drilling, welding, cutting, marking and fine-tuning, evaporation, crushing and local heat treatment. Its application area has been involved in various fields of science and technology, especially for the electronics industry, precision instruments, aerospace and machinery industries play a catalytic role. In the past two or three years, laser processing technology has made rapid progress and has reached the practical application level in several industrial fields. One of the main reasons is that the price of solid-state laser processing equipment has dropped, reliability, stability, tunability and reproducibility
