摘要：

We demonstrated a 1.21-W 532-nm picoseconds (ps) green laser via second-harmonic generation (SHG) using type-I phase-matched K3B6O10Cl (KBOC) as a nonlinear optical crystal. The ps green laser was successfully generated from two types of 1064-nm ps lasers with one being operated at 10 kHz and the other at 10 Hz. Using a 7.38-W pumping power at 10 kHz as the pump, the SHG output power at 532 nm was 1.21 W with a pulse width of 34.4 ps. For the 10-Hz ps laser with pumping energy of 4.95 mJ per pulse, the output at 532 nm was 1.78 mJ per pulse, which corresponds to an optical conversion efficiency of 36.0%. The experimental results show that the KBOC crystal is a promising nonlinear optical crystal for generating ps green laser. (C) 2018 Society of Photo-Optical Instrumentation Engineers (SPIE)
