二氧化碳激光器（CO₂激光器）

有源晶振（石英晶体振荡器）主要应用于工业设备中，如数字系统、数控机床设备、数控激光切割机、钣金设备、印花设备、锁相环系统、调制解调器、船舶、电信、传感器以及磁盘驱动器等中。

以二氧化碳激光器（CO₂激光器）为例：

二氧化碳激光器发出的激光波长为10.6 微米，“身”处红外区，肉眼不能觉察，它的工作方式有连续、脉冲两种，用于激光切割，焊接，钻孔和表面处理。

二氧化碳激光器的功率分为高功率和低功率两种。高功率CO2激光器作为商业应用激光可达45千瓦，这是最强的物质处理激光，经常用来做工业的切割机，而低功率激光器常常用来雕刻。此外，由于水在二氧化碳激光器的发光频率极容易挥发，因此也常常被用来做激光嫩肤 ，磨皮等激光手术。

高功率CO2激光器常用到的晶振为电压为5V，输出负载为30pF的大功率有源晶振，以晶诺威科技产OSC7050有源晶振100MHz为例，其规格参数如下：

Laser cutting technology is a non-contact cutting process that uses a high-power laser beam to cut various materials, including metals, plastics, ceramics and composite materials. The laser beam is generated by laser source and focuses beam on material through a series of mirrors and lenses. The laser beam melts, vaporizes or burns the material to form a narrow slit with high precision and accuracy. Laser cutting is a highly versatile process which can cut materials into various thicknesses and shapes, including straight lines, curves, angles and contours.

激光切割技术是一种非接触式切割工艺，利用高功率激光束切割各种材料，包括金属、塑料、陶瓷和复合材料等。激光束由激光源产生，并通过一系列的反射镜和透镜聚焦在材料上。激光束将材料熔化、蒸发或燃烧，以极高的精密度和准确度形成窄缝。激光切割是一种高度通用的工艺，可以将材料切割成各种厚度和形状，包括直线、曲线、角度和轮廓。
