The Physical Properties of Birefringent Dual-Frequency Lasers
摘要
The first chapter has described the light sources successfully developed by the team: gas birefringent lasers (He-Ne) and microchip solid-state lasers (Nd:YAG and Nd:YVO4). This chapter describes the characteristics of these lasers, including mode competition, orthogonal polarization, cavity length tuning (variation), frequency difference tuning, and feedback effects of orthogonal polarization lasers. The observed phenomena are very rich and beyond our expectation. These phenomena became the physical basis for the invention of a series of instruments in Chaps. 3 and 4 .
