Laser Systems and Atomic Transitions

This lecture covers the modules of the 2013 course on laser operation, laser systems, noise characteristics, optical fibers, modulation techniques, ultrafast lasers, and nonlinear frequency conversion. It also delves into atomic transitions, gain, and the electron oscillator model. The instructor explains the amplification process of light, the atomic structure, and the operation of a ruby laser. Furthermore, the lecture discusses the absorption coefficient, refractive index, and Doppler broadening of spectral lines in the Lorentz model.
