同轴型CO_2激光器容易获得适于精密加工的低次横模束,不过它的缺点是单位放电长度的激光输出功率较小,谐振腔体积较大。为此,松下公司致力于小型谐振腔的研制,并努力提高单位放电长度的输出功率。所研制出来的谐振腔,单位放电长度的输出功率超过已往的4倍,而且可靠性高,价格低廉。用这种振荡器对脉冲输出在加工中的效应进行了研究,并由此制作了精密加工的CO_2激光加工系统。最近,用激光加工的方法受到高度重视,通过工作方式的研究以及外围设备的充实,可望在更多的工厂中得到广泛应用。
Coaxial CO2 laser is easy to obtain low-order transverse beam suitable for precision machining. However, its disadvantage is that the laser output power per unit discharge length is small and the cavity volume is relatively large. To this end, Panasonic is committed to the development of small resonators, and strive to improve the unit discharge length of the output power. Developed by the resonant cavity, the unit discharge length of the output power of more than 4 times the previous, and high reliability, low prices. The effect of pulse output in machining was studied by using this oscillator, and the precision machining CO_2 laser processing system was fabricated. Recently, the laser processing method has been highly valued, through the study of working methods and the enrichment of peripheral devices, is expected to be widely used in more factories.
