Learning goals

Knowledge
Optical frequency multiplication (crystal coherence lengths, phase matching,
quasi phase matching and periodic polarity)
Frequency mixing
Optical-parametric oscillation and amplification
Electro-, magneto- and acousto-optical effects
Q-switch, mode coupling, ultrashort pulse laser
Application of multiphoton processes
Photorefraction, stimulated Brillouin scattering, phase conjugating mirrors

Skills
Recognizing analogies of known linear physical processes (light-matter interaction at low intensity) and transferring them to nonlinear processes
Describe processes mathematically and transfer the result into physical effects
Transfer idealized systems to real systems and derive qualitative behavior
Describe and explain correlations of quantities (saturable absorption / multidimensional refractive index) and transfer them to real materials.
Analyze technical applications and problems, break them down into individual processes and solve them using known nonlinear interactions.
