Περιγραφή Μαθήματος

This course explores the fascinating regime of physics where the linear approximation of light-matter interaction breaks down. Nonlinear Optics (NLO) examines how intense electromagnetic fields—typically from lasers—alter the optical properties of a medium, leading to phenomena where light can change its own frequency, modulate its shape, or even interact with other light beams.

We will cover fundamental concepts including the nonlinear susceptibility tensor, wave-mixing processes (SHG, SFG, DFG), the optical Kerr effect, and multiphoton absorption. By the end of the term, you will understand the principles behind modern photonic technologies, from ultrafast pulse generation to quantum light sources.

Grading Systems

To provide flexibility and reward consistent effort, the final grade is calculated using two different pathways. Your final grade will be the maximum of these two options:

Option 1: Continuous Assessment

This path favors students who engage with the material throughout the semester.

• 30% Homework & Oral Defense: You will receive a score for your written homework (H). This score is then scaled by a coefficient (C) between 0 and 1, determined by a brief oral examination regarding your submitted work.

  Example: If you earn 100% on homework but receive an 0.8 in the oral defense, your component score is 30% x 0.8 = 24%.

• 20% Topical Presentation: A ~30-minute comprehensive presentation on a specialized NLO topic. Topics must be chosen by the student and approved by the professor in advance.
  
  

• 50% Final Exam: A comprehensive examination. You are permitted to bring 50 pages of self-prepared notes.

  • Note: These must be self-prepared and preferably handwritten; photocopies or printed materials are not allowed.

Option 2: Final Exam Focus

This path is available for those who prefer to be assessed solely on their performance at the end of the term.

• 100% Final Exam: The grade is determined entirely by the final examination score.
