Frequency Doubling Crystal
| Frequency Doubler or Second Harmonic Generation (SHG) is a special case of sum frequency generation if the two input wavelengths are the same. The simplest scheme for frequency doubling is extracavity doubling. The laser passes through the nonlinear crystal only once. However, if the power density of laser is low, focused beam, intracavity doubling and external resonant cavity are normally used to increase the power density on the crystals. | ||
