摘要：

It not only needs space match but also needs timing match of pumping laser and dye laser seed in pulsed dye laser master-oscillator power-amplifier (MOPA) chain which employs more than one diode-pumped-solid-state lasers (DPSSL). So a laser pulse timing control method is reported to realize the timing match of pumping laser pulse and the seed laser pulse. The computer data acquisition of fast laser pulses is realized through fiber, fiber switch and random repetitive sampling technologies. When the pumping pulse and seed pulse are timing match, their peaks are almost superposition. So the laser pulse delay time is measured at its peak point to eliminate the influence of pulse-width change. The noise at laser pulse peak point is eliminated using binominal curve fitting in data process. This control system realizes the laser pulse timing measurement and close-loop control in nanosecond rank. The single step control error and measurement error are less than ±0.2 ns. The close loop control precision is ±1 ns.
