High repetition rate short pulsed compact solid state lasers pumped by laser-diode （LD） are promising and compellent in many applications such as laser machining, free space laser communications, spaceborne lidar, and laser ranging. Electro-optic （EO） Q-switching has been approved an effective method to obtain stable output with high peak power, narrow pulse width and small pulse-to-pulse amplitude fluctuation. Recently, with the development of new types of electro-optic crystals, the repetition rate of EO Q-switched solid state lasers has been improved significantly. The recent progresses of high repetition rate EO Q-switched solid state lasers are introduced in detail.
