WebThe key issue in GRENOUILLE is the crystal thickness. Ordinarily, achieving sufficient phase-matching bandwidth requires minimizing the group-velocity mismatch, GVM: the fundamental and the second harmonic must overlap for the entire SHG crystal length, L. If p is the pulse length, GVM 1/v g ( 0 /2) – 1/v g ( 0) v g Web1) Crystal thickness The fundamental frequency is inversely proportional to the thickness, h, of the crystal disk, eq. (1). The higher the fundamental frequency, the thinner the crystal. For example, a 5 MHz QCM crystal will have a thickness of ~334 um, and a 10 MHz crystal will be half that, and have a thickness of ~167 um.
