Abstract

Third-harmonic generation (THG) with high output power based on the type-I phase-matching La₂CaB₁₀O₁₉ (LCB) crystal was investigated in yz plane (θ=48.7°, φ=90°), in which direction the effective nonlinear coefficient (d_eff) of LCB is 0.7, much larger than the previous reports in other direction. The maximum output power we obtained at 355 nm was as high as 11.5 W, and the beam quality was measured to 1.47 in x direction and 2.56 in y direction. The angular bandwidth and temperature bandwidth in this direction were measured, which are larger than the previous reports also.
