Abstract

In interferometry measurement of density of plasma induced by pulsed laser, the external triggering signals are used to trigger flash lamp and Q-switch of main laser (Nd:YAG) and probing laser (N2 dye laser), in order to eliminate the jitter, a pre-delay unit and two delay units are used to get the delayed triggering signals for Q-switch of main laser and probing laser respectively, another innovative design is to replace the wollaston prism with a biprism, so that the polarizer and analyzer can be exempted, the loss of probing light can be lessened, and image of higher resolution can be achieved.
