QUANTUM ELECTRONICS

Quantization of EM field (secondary quantization, field modes, energy of quantized EM field, spontaneous and stimulated transitions). Optical resonators (Fabry-Perot etalon, mode stability, resonance frequencies, losses, unstable resonator). Interaction of radiation with atomic systems. Basic theory of laser (pumping, efficiency, three and four level lasers, mode locking, Q–switch). Laser systems (Ruby, YAG, semiconductor injection laser, He-Ne laser).
