Fourth-harmonic generation in a single lithium niobate-crystal with cascaded second-harmonic generation

Published

Journal Article

Tunable second- and fourth-harmonic radiation was generated in a single 1-cm-long lithium niobate (LiNbO3) crystal with the Mark III infrared free electron laser at Duke University. The fundamental laser radiation was tuned from 2 to 2.5 μm, yielding 1-1.25-μm radiation (second harmonic) and 0.5-0.625-μm radiation (fourth harmonic). A fundamental-second-harmonic energy conversion efficiency of 66% and a fundamental-fourth-harmonic energy conversion efficiency of 3.3 × 10-6 were measured. The maximum energy in the fourth harmonic was 3.3 nJ. © 1994 Optical Society of America.
