Abstract:
In this paper, we develop a constructive algorithm to determine the parameters of a nonlinear crystal for generating correlated photons in a given wavelength range using the effect of spontaneous parametric scattering. The developed method is used to calculate the parameters of a barium beta borate crystal capable of generating biphoton radiation in the wavelength range from 0.548 to 1.55 μm at a pumping wavelength of 0.405 μm. The experiment that confirms the method's efficiency is described.
The work was performed using the equipment at the facilities of the Center of High-Precision Measuring in Photonics (ckp.vniiofi.ru), All-Russian Research Institute for Optical and Physical Measurements. This work was supported by the Ministry of Education and Science of Russia, agreement no. 14.595.21.0003 (unique identifier RFMEFI59517X0003).
