COATING FOR OPTIMISING OUTPUT COUPLING OF EM RADIATION
摘要
A coating (10) between a nonlinear crystal (5) and a silicon prism couple r (9), prevents transmission of radiation scattered within the crystal (5) b y filtering out frequencies outside the silicon bandgap to avoid free carrie r absorption, but transmits THz frequencies that correspond to the bandgap.
