Summary

This course gives an introduction to Lasers by both considering fundamental principles and applications. Topics that are covered include the theory of lasers, laser resonators and laser dynamics. In addition to the basic concepts, a variety of interesting laser systems and applications are covered

Content

1. Introduction (Overview: History of the laser, Market application, Nobel Prizes,)- demo laser printer.

2. Basics of resonators and Gaussian beam optics.

3. Principle of laser operation: Lorentz model, dispersion theory.

4. Principle of laser operation: Laser oscillation, threshold, coherence.

5. Semiconductor and photonic nanostructured lasers

6. Laser dynamics : Laser oscillation, laser line-width, coherent population oscillations - AM, PM Noise.

7. (Gas and ) Solid state lasers Optical fibers

8. Fiber laser and amplifiers Optical fibers

9. Ultrafast lasers, Femtosecond laser Frequency Metrology, Mode locked lasers, autocorrelation, FTIR

10. Ultrafast lasers, Femtosecond laser Frequency Metrology, Mode locked lasers

11. Detection of laser light (detector basics)

12. Optical parametric oscillators (OPO), Raman Lasers

13. Tools of laser light manipulation

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:

• Able to compute absorption cross-section
