Abstract
Parallel excitation of optical parametric oscillations was observed on PPLT dispersed with tri-QPM structures in the transverse direction to a nano-second pump beam. It led to simultaneous IR generation from 1000 to 1150nm with slope efficiency > 30%. When a nonlinearly-chirped PPLT was subject to such IR pump, it exhibits simultaneous broad green generation from 500 to 560nm with single pass efficiency ~10%. This was due to broad spectral coverage of QPM-SHG and SFG in the chirp structures.
