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.conference paper2-s2.0-85136440822https://api.elsevier.com/content/abstract/scopus_id/85136440822
