Abstract :
Summary form only given. Q switching utilizing saturable absorption does not require an external driver; however, the power output and repetition rate are not stable. Acousto-optic or electro-optic (EO) Q switching exhibits more stable performance but requires high rf power or kilovolt voltage due to the small modulation efficiency of KDP and LiNbO/sub 3/. In this paper, we present an innovative PLZT-based EO Q switch. Due to its large EO coefficient, a drive voltage of only 300 V to Q switch a 1.06-/spl mu/m Nd:YVO/sub 4/ laser was measured.
