Sum-frequency and different-frequency generation - Phase matching

      "Sum-frequency and different-frequency generation - Phase matching" allows you to select the crystal for THG, FHG, SFG, DFG, OPA and OPO and to calculate all integral parameters: phase-matching angles, phase-matching amplification angular (internal and external) width, phase-matching amplification wavelength width, phase-matching amplification temperature bandwidth, "walk-off" angles, effective nonlinear coefficient, and other.



Phase-matching angles dependensies for all possible types of interaction

      You can computate the tuning characteristics versus wavelength of pumping radiation, temperature and angles of orientation of a crystal.
