Abstract
We observed cw third-harmonic generation in a periodically poled LiNbO3 crystal by cascading optimally phase-matched second-harmonic and sum-frequency generation. Other processes, such as fourth-harmonic generation, are allowed by the flexibility of quasi-phase matching. We demonstrate a divide-by-nine (1.19–) frequency chain that uses only two lasers.
