摘　　要：A novel beam-steering external cavity diode laser using an intracavity lead lanthanum zirconate titanate （PLZT） electro-optic ceramic deflector is proposed and demonstrated experimentally. The laser consists of a semiconductor laser with single mode fiber coupled output, polarization controller, PLZT electro-optic ceramic deflector, and output concave mirror. By applying proper driven electrical signals on the PLZT electro-optic deflector, the beam deflection angle achieves 5.8 mrad at 1 000 V. A high-speed beam-steering property with less than 120-ns switching time is also observed. Moreover, a good beam quality withA novel beam-steering external cavity diode laser using an intracavity lead lanthanum zirconate titanate （PLZT） electro-optic ceramic deflector is proposed and demonstrated experimentally.
