Nonlinear crystals for frequency conversion
Résumé
Crystals can convert wavelengths emitted by lasers using a second-order process. They allow light to be generated with smaller or higher wavelengths than those of the input beam. The issue is to select the nonlinear crystal having the best conversion efficiency at the targeted wavelengths, which requires a high non-linearity and suited transparency range as well as phase-matching conditions.
