A novel high-energy picosecond optical parametric oscillator (OPO) was realized by placing an OPO in a second-harmonic (SH) cavity. In a proof-of-principle experiment, excellent burst energy of 45 mu J for the OPO signal at 900 nm was demonstrated, operating at a pulse repetition rate of 10 kHz and a pulse width of 46.8 ps. The measured beam quality showed good performance with a beam factor M-2 = 1.42.
A novel high-energy picosecond optical parametric oscillator (OPO) was realized by placing an OPO in a second-harmonic (SH) cavity. In a proof-of-principle experiment, we demonstrated excellent burst energy of 45 mu J for the OPO signal at 900 nm that operates at a pulse repetition rate of 10 kHz and a pulse width of 46.8 ps. The beam quality was measured as M-x(2) = 1.44 M-y(2) = 1.40 in the orthogonal directions, corresponding to an average beam factor M-2 = 1.42. So far, this study is the first to investigate high-energy ps OPO synchronously pumped in a second-harmonic cavity.
