0026 // Class Description:
0027 // G4QuasiOpticalPhoton is a non-physical particle definition designed to
0028 // encapsulate the conditions for generating a burst of optical photons in
0029 // processes such as scintillation or Cerenkov radiation. Its role is to serve
0030 // as a compact carrier of optical emission metadata—stored via
0031 // G4VUserTrackInformation—including the number of photons to generate, parent
0032 // particle charge, information about the step and track state, and associated
0033 // material properties. This enables deferred or offloaded optical photon
0034 // production and propagation, particularly for hybrid or heterogeneous
0035 // workflows. The term *quasi* (suggested by Daren Sawkey) refers to the
0036 // particle’s representation as a collective distribution of optical photons-
0037 // a synthetic construct used to manage secondary particle generation in the
0038 // Geant4 tracking and optical processes.
