研制了双通道、双波长共电极的射频波导CO2激光器,激光器采用双通道共电极结构,每一通道用光栅选频输出,可用压电陶瓷(PZT)控制激光腔长,以调节激光频率以及脉冲激光建立时间。两个通道同时获得了不同波长的脉冲激光输出,通过调节PZT上的电压使双通道输出脉冲激光达到同步,激光器不仅结构紧凑、体积小,而且具有很高的脉冲同步几率。 A dual-channel, dual-wavelength, common-wave RF waveguide CO2 laser is developed. The laser uses a dual-channel common-electrode structure. Each channel is selectively output with a grating. PZT can be used to control the laser cavity length to adjust the laser frequency and pulse Laser build time. The two channels receive the pulsed laser output with different wavelength at the same time. By adjusting the voltage on the PZT, the dual-channel output pulsed laser can be synchronized. The laser has the advantages of compact structure, small size and high pulse synchronization probability.
