最近十年来以扩散冷却为特征的横向射频激励ＣＯ２激光器发展非常迅速，有取代传统工业用ＣＯ２激光器的趋势。国际上，目前已有几瓦到几百瓦的系列产品，千瓦级产品也正在开发中。此类激光器完全摒弃了流动冷却的束缚，不再需要高速风机和庞大的热交换器、结构大为简化。... Lateral RF-excited CO2 lasers, characterized by diffusion cooling, have been developing very rapidly in the last decade and have the potential to replace traditional industrial CO2 lasers. Internationally, there are currently a few watts to a few hundred watts of products, kilowatts-class products are also being developed. Such lasers completely abandon the flow of cooling constraints, no longer need high-speed fan and a huge heat exchanger, the structure is greatly simplified. ...
