Focusing on the growing demands for number and quality of laser beams,a novel me thod of laser beams splitting based on Wollaston prisms is proposed. In this method, a single femtosecond laser pulse beam is transformed into pulses of multi- angle transmission with femtosecond or longer interval using Wollaston prisms and two lenses.The angles of laser beams splitting can be adjusted flexibly,the energy utilization rate is high,and its structure is simple.A setup of femtosecond laser holographic recording system is constructed on the basis of the approach,and the four-way multiplexing interference fringes are recorded. The experimental results show that the proposed system can be applied in ultrafast holographic re cording system.
