Thank you for your help Michael Kelsey.

I will try to extend these tables in order to fall under 1,96eV. However, I have already generated optical photons with an energy of 3eV and moreover. Sadly, the same absorption length is computed.

Concerning the primaries particle, I define "OpticalPhoton" :

PrimaryGeneratorAction::PrimaryGeneratorAction()
  {
  G4int n_particle = 1;
  particleGun = new G4ParticleGun(n_particle);

  G4ThreeVector Polarization = G4ThreeVector(1.,1.,0.) ;
  particleGun->SetParticlePolarization(Polarization);

  particleGun->SetParticleDefinition(G4OpticalPhoton::OpticalPhotonDefinition());
  particleGun->SetParticleEnergy(3*eV);
  }

void PrimaryGeneratorAction::GeneratePrimaries(G4Event* anEvent)
  {
  G4ThreeVector v(1.0,0.0,0.0);
  particleGun->SetParticlePosition(G4ThreeVector(1*mm, 0*cm, 0*cm));
  particleGun->SetParticleMomentumDirection(v);
  particleGun->GeneratePrimaryVertex(anEvent);
  }

Thank you again your your answer.
