Abstract

Abstract

We analyze the stray light caused by surface scattering of the sum-frequency crystal in third-order correlation measurement and its influence on the contrast of the sum-frequency light. Besides, the expression of the stray light caused by surface scattering is given. When the surface roughness is 1% of the laser wavelength, the intensity of stray light reaches about 10-8. And the rougher the surface is, the more stray light it causes.
