射频横向激励扩散型冷却大功率CO_2激光器技术是国际上90年代出现的最新技术,目 前只有少数几个国家掌握。这种激光器具有体积小、光束质量高、总效率高、成本低和机动性好等优点,具有广阔的应用前景。 射频横向气体放电激励技术与目前采用的传统的直流气体放电激励技术相比有如下优点:(1)射频波可实现高频幅度调制,因而可高频调制激光增益获得方波激光输出,其调制频率可达200kHz,可实现带前沿尖峰的方波输出(superpulse),这是直流放电激励方式所
RF Lateral Excitation Diffusion-type cooling high-power CO_2 laser technology is the latest international technology emerged in the 90s, at present only a few countries have mastered. The laser has the advantages of small size, high beam quality, high total efficiency, low cost and good maneuverability, and has broad application prospects. Compared with the traditional DC gas discharge excitation technology currently used, the RF transverse gas discharge excitation technology has the following advantages: (1) RF waves can realize high-frequency amplitude modulation, so that the square wave laser output can be obtained by high-frequency laser gain modulation Frequency up to 200kHz, can be achieved with a sharp peak of the square wave output (superpulse), which is the DC discharge excitation mode
