A superradiant laser based on two-photon Raman transition of caesium atoms
Pengfei Liu, Yu Peng
We propose a superradiant laser based on two-photon Raman transition of caesium-133 atoms which collectively emit photons on an ultra narrow transition into the mode of a low Q res…
A novel scheme for simple and precise measurement of the complex refractive index and thickness of thin films
Yu Peng
We demonstrate applications of a novel scheme which is used for measuring refractive index and thickness of thin film by analyzing the relative phase difference and reflected ratio…
A novel scheme for hundred-hertz linewidth measurements with self-heterodyne method
Yu Peng
We propose a novel scheme for accurately determining hundred-hertz linewidth by delayed self-heterodyne method in which delay time far less than the laser's coherence time. That ex…
A novel scheme for measuring the relative phase difference between S and P polarization in optically denser medium
Yu Peng
We demonstrate applications of a novel setup which is used for measuring relative phase difference between S and P polarization at oblique incidence point in optically denser mediu…
