Harmonic Generation
This article explained what is harmonic generation (or frequency conversion), which is the result of the utilization of nonlinear optical effects, and other contents including type I, type II phase matching.
Categories of Optical Crystalline Birefringence Polarizers
An Optical Polarizer is an optical element that screens light and split it into two beams with a specific ratio according to its polarization state. This article unfolds a basic concept and working principles of different categories of birefringent crystal polarizers including Glan polarizers (Glan Thompson, Glan Taylor), Wollaston Polarizers, and Rochon Polarizers. In the text, we also introduced two kinds of optical parts related to polarization: Polarization Rotator and Depolarizer.
