Yang Han · Journal of Optoelectronics·laser · 2010
A FPGA-based dual-laser synchronization control system used in the nanosecond-pumped laser system is realized.The 2-frequency division of the 20 Hz synchronized signal from the femtosecond-laser is produced for triggering the fiber spectrograph.Meanwhile,according to the delay time set by the PC,the signals for triggering the nanosecond-laser are generated,including the lamp triggering signal and the Q-switch signal.The principle of the nanosecond pump detection system for the application of double-laser synchronizing control is described.The design of each module is presented in detail,and the analysis on the triggering signals of each channel from the experiment shows that it is feasible.
