Abstract

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.
