The generation of beams with a double frequency (i.e. half wavelength) or other multiple frequencies is done with so-called nonlinear crystals. Various crystal materials are available, with varying crystal structures, wavelength acceptance and thermal properties. BBO, LBO, KTP, LiNbO3, KDP, KD*P and RTP are all offered in custom configurations to suit custom applications.
Typical applications for nonlinear crystals:
- Frequency multiplication (SHG, THG)
- Frequency mixing (SFM, DFM)
- Optical parametric oscillators/amplifiers (OPO/OPA)
- Electro-optical components (Pockels cells, Q-switches)
