摘　　要：高功率激光装置三倍频时间波形测量采用无畸变的光栅衍射取样技术、高速光电管和示波器探测设备及多通道复用技术,给出了靶场多路三倍频光束的高时间分辨和高动态范围的时间波形测试,详细的测试技术和方法分析对高功率激光装置三倍频时间波形精密诊断提供技术支撑。The temporal profile of frequency tripled beam of the high power laser facility is measured using the distortionless sampling by the diffraction of the beam sampling grating, transient photodiode,high-speed digital oscillograph and the multiplexing technology of multichannel. The high resolution and dynamic range of the temporal profiles of frequency tripled beam is obtained. The detailed measurement technology and methods are important for the precision diagnosis of the temporal profile measurement system of frequency tripled beam of the high power laser facility.
