Phase-matched third harmonic generation in ABN crystals at λ=1.064µm

A type II phase-matched third harmonic generation in an organic single crystal of 4-aminobenzonitrile has been studied. A Q-switched, mode-locked Nd-Yag laser at 1.064 µm has been used in the experiments. Direct comparison with a phase-matched type II THG from a BBO crystal shows that the UV signal in ABN is 50 times larger than in BBO
