Monolithic integration of collimating Fresnel lens for beam quality enhancement in tapered high-power laser diode

The Study of Beam Collimating, Optical Index of Refraction and Birefringence Measurement

“…As we know, the study of light is one of the oldest sciences. After figure out the basic knowledge of light, we can not only get the energy from light, but also use light help scientist study the performance of many materials [1].This paper could help us understand the basic optical principles in coherent optics and focusing on to learn the use of optical components such as lenses, pinholes. Also, configuring optical experiment that depends on collimated coherent light.…”
