Abstract
A photon beam generating apparatus comprises an incident pump beam generation section and a photon pair generation section including a non-linear optical medium The angle between the optical axis of the medium and an incident pump beam is set to a value such that tuning curves become tangent to a line corresponding to a wavelength a in order to generate two photon beams including paired photons generated simultaneously and having a wavelength a. Another photon beam generating apparatus comprises an incident pump beam generation section and a photon pair generation section including a non-linear optical medium The angle between the optical axis of the medium and the incident pump beam is set to a value such that tuning curves become tangent to different lines corresponding to wavelengths a and b respectively, in order to generate two photon beams including paired photons generated simultaneously and having wavelengths a and b respectively.
