5、热处理和激光熔覆设备的用户进行调查，很多用户反映设备性能较差，大部分情况为：设备稳定性很差，年故障次数5次以上；激光器使用一至两年后出现功率输出变小、模式变差，因此造成大部分成套设备经常处于低性能状态，甚至停运。主要问题集中在激光器的关键技术指标达不到标准。2.

7、, or eve n outages. Laser focus on key issues in the key in dicators-sta ndard tech no logy.千瓦级大功率 CO2激光器存在的主要问题及描述序号主要问题简单描述激光器无法在额定功率下稳定运行，最高功率只能在额定功率的60%下运行（如5000W横流CO2激光器可以稳定运行的功率激光功率“大打折扣”，影响加工效率仅为3000V）也有显示的功率数偏高的现象；如5000W横流CO2激光器功率计显示输出功率为5000W按计量局标准的手持功率检测仪器显示仅为 3000W因此，很多高功率设备处于低功率运行状态，加工效率

8、降约为标准的一半。根据行业技术标准的规范，合格的横流CO2激光器可以获得 多模和低阶模两种激光束模式，低阶模状态的功率为多模的1/2。低阶模状态性能目前国内的大部分横流 C02激光器通过加“光栅”取得低阶 差，无法开展新业2模状态，只能获得多模功率的1/3左右；按照上面多模激光输出务（激光焊接、激功率情况，以5000W的横流C02激光器为例，在低阶模稳定运行 光切割）状态下，只获得1000W左右（按技术标准可获得低阶模2500W。因此，大部分已投入生产的横流 C02激光器的仅采用多模光束，几乎没有开发低阶模及环形模的激光焊接应用技术。设备运行过程中，经常出现光路偏差、电路故障等问题，影 响生产

9、进度。激光器稳定性差经过调查分析，激光器的谐振腔稳定性差， 容易出现光轴漂序号主要问题简单描述电路板控制，稳定性差；放电系统产生的增益区小。对于复杂的熔覆工艺，大部分激光设备客户采用重力送粉机4工艺装备差构，进行铺粉或预置粉末的办法；无法对复杂形状的零部件进行三维送粉和修复。1kw-class high-power CO2 laser and the main problems describedMain issues No.BriefLasers can not be rated power un der the stablepowerCO2operati onof power only i
