A high energy all-solid-state blue laser with wavelength of 455 nm is proposed, which can be used in laser communication underwater or in the differential absorption lidar (DIAL) system. Ti:sapphire crystal is suitable material and is pumped by the second harmonic generation (SHG) of Nd:YAG laser. The pumped laser of 1000 mJ, 10 Hz is used, and the output wavelength of Ti:sapphire resonator cavity is controlled by external injection seeding. Parameters of the resonator cavity of Ti:sapphire crystal is carefully calculated and optimized. Pulsed 455-nm blue laser exceeding 100 mJ is obtained through frequency-doubled Ti:sapphire laser.
