不加腔外展宽器的高重复率钛宝石再生放大器

最近我们在省略腔外展宽器的放大器中实现了自锁模钛宝石脉冲的放大,实验中我们用自制的的振荡器产生脉宽为20f.

PRACTICAL CIKCUIT OF NANOSECOND LASER DOUBLE PULSES WITH SHOKT INTERVAL AND HIGH PRECISION

An electric control system of Transient Laser Holography Testing Device is introduced in this paper. It is designed and calculated strictly by using a clock circuit with a frequency of 10MHz and leading a clock signal with a frequency of 1MHz into the gate control circuit.The possibility of the random error of 0.1μs has been eliminated and the precision of theSystem achieves to(1～9)±0.1μS. Each of the output of the double pulses has;almost the same energy. The ability of anti-interference is good.The success rate of experiments is high. The system can be used to measure speed,shape,size and distribution of a particles in the particle field and a good result can be obtained.
