摘　　要：一台具有良好光学质量的工业用5kW级横流CO_2激光器研制成功。该激光器具有独特的预电离电极结构和光腔选模技术,一次充气连续密封运转大于10h,功率不稳定度为±1.0％,存放工作寿命大于1个月。利用该激光器进行汽车齿轮焊接试验,熔深可达3～4mm,焊接速度为2m/min,深、宽比可达2.5:1。An industrial 5 kW level transverse-flow CO2 laser has been developed with good beam quality. The laser features a unique preionization electrode structure and mode-selecting technique. Sealed-off CW operation for more than 10hrs can be obtained for each gas refilling with a power unstability of ±1.0% and a shelf life of one month. A welding depth of 3-4 mm at 2 meters per minute can be achieved for the automobile gears with a depth to width ratio of 2.5:1.
