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
