Laser fundamentals and applications for engineers
Summary
The course will cover the fundamentals of lasers and focus on selected practical applications using lasers in engineering. The course is divided approximately as 1/3 theory and 2/3 covering selected applications.
Content
1. Introduction, history of the laser, overview market applications, basic laser operation I: dispersion, Lorentz model.
2. Basic laser operation II: Gain and resonators (spatial mode and longitudinal modes)
3. Laser systems I: most common solid state lasers and gas lasers
4. Detection of light: detector noise and laser Noise, AM, PM Noise.
5. Laser systems II: low and high power semi-conductor lasers, beam quality, beam combiners. Applications
6. Laser systems II: low and high power semi-conductor lasers, beam quality, beam combiners. Applications
7. Laser systems II: low and high power semi-conductor lasers, beam quality, beam combiners. Applications
8. Laser beam steering: theory, applications, printing
9. Laser systems III: Optical fibers and fiber lasers
10. Ultrafast lasers I: Femtosecond laser, modelocking. Two photon imaging, ablation.
11. Ultrafast lasers II: pulse characterization. Two photon 3D fabrication.
12. Non-linear frequency conversion I: frequency doubling. Applications
13. Non-linear frequency conversion I: Optical parametric amplification, OPA .
14. Lab tour
Learning Prerequisites
Important concepts to start the course
This course requires an understanding of introductory physics in wave theory (incl. complex numbers) and familiarity with Maxwell equations and electromagnetism.
Learning Outcomes
By the end of the course, the student must be able to:
- Explain 1. Explain the basic working mechanism and characteristics of each lasers introduced. 2. Select a particular laser system adapted to an application.
- Select appropriately Select a particular laser system adapted to an application.
Assessment methods
The course grading is based on a final oral exam which counts for 80% of the grade and two quizzes during the semester which count for 20% of the grade.
