  4. CH1 Nature of light

  5. Wave-particle duality Photons • E=hν • =h / p • Light behaves like waves in its propagation and in phenomena of interference and diffraction; • However, it exhibits particle-like behavior when exchanging energy with matter, as in the Compton and photoelectric effects

  6. E = mc2 + Ek • rest-mass kinetic • energy energy • Photon m=0 zero rest mass

  7. Electrons obey Fermi-Dirac Statistics no two e- in the same state, same physical properties • Photons obey Bose-Einstein statistics identical photons with the same energy, momentum, and polarization can occur together in large numbers

  8. ν c=ν Ex 1-2

  9. Irradiance W/m2 Radiant intensity W/sr sr: steradians

  10. Lambert‘s cosine Law If radiance is constant at each angle  Perfectly diffuse，Lambertian surface radiate uniformly in all directions

  11. If dΦ1＝ dΦ2 L1＝L2

  12. Page 14 Ex1－3 • Consider a Φe＝5mW He－Ne laser emitting a beam with a divergence angle αof 1.3mradians. The laser cavity is designed so that the beam emerges from a surface area ∆As=2.5x10-3 cm2 at the output mirror. • Determine the solid angle ∆ in term of R and α. • Determine the radiance of this laser light source in units of
