介绍了一种基于计算机与单片机联合控制的光泵浦脉冲产生系统,该系统主要工作于低频率长周期种子光源的放大驱动。系统采用半导体激光器发出的光脉冲作为光放大器的泵浦光源,能通过计算机或手动调整半导体激光器泵浦的输出功率、脉冲宽度、脉冲间隔,并同步/延时触发种子光源,可用于中、大功率光放大器的应用研究。与现有采用纯定时电路的光放大驱动系统相比,该系统具有可计算机远程控制、可数字化控制、可与外电路同步、电路简单稳定、体积小等优点,已稳定使用一年多。
An optical pumping pulse generation system based on computer and singlechip control is introduced. The system mainly works on the amplification and driving of low frequency and long period seed light source. The system uses the light pulse emitted by the semiconductor laser as the pump light source of the optical amplifier and can be used to adjust the output power, pulse width and pulse interval of the semiconductor laser pump by a computer or manually and to synchronize / delay the seed light source to be used for medium and large Application Research of Power Optical Amplifier. Compared with the existing optical amplifier driving system with pure timing circuit, the system has the advantages of computer remote control, digital control, synchronization with external circuits, simple and stable circuit and small size, and has been used for more than one year.
