Electro-optic Q-switched diode pumped solid-state laser (DPL) with corner-cube,cross-resonator optical parametric oscillator (OPO) (CRO) and the technology of polarization controlled by electricity are used to acquire the output of dual-wavelength of 1064 nm and 1570 nmin the conditions that the laser must be smart and light,and have high reliability,high efficiency,high recurrence-frenquency and large power output.Experiment gets laser pulse with 200 mJ each pluse at 1064 nm and 74 mJ each pluse at 1570 nm,and conversion efficiency of 45% together with output of stable orientation,so that it can be used as airborne,spaceborne,ship laser location,irradiation or radar,and used in the field of laser environmental monitoring.
