Major topics of the course: Electromagnetic fields, Maxwell equations, wave equation. Interfer-ence, diffraction. Electromagnetic waves in materials. Interaction of light and matter, quantum phe-nomena. Quantum theory of atoms and molecules. Statistical physics, Maxwell-Bolzmann, Fermi-Dirac statistics, electrons in solids. Bose-Einstein statistics, photons in thermal equilibrium, photons and material interaction in thermal equilibrium. Introduction to lasers. Interaction of light and matter (phenomenological description), line broadening mechanisms. Optical coherent amplifier, gain, bandwidth, phase, power source, nonlinearity (saturation) and noise. Passive optical resonators, properties of the Gaussian beam, transmission through optical components. Laser operation: cw, transient. Semiconductor lasers. Laser systems and applications. Laboratory visits.


Attendance requirement: 70% of lectures, 100% of seminar attendances and laboratory visits are compulsory.

Conditions for the signature: Successful test (above 40% of the achievable maximum) on week 12 on seminar. Non-successful test can be repeated once in the retake-week. Rating of the test result:
40 -  54%    pass (2)
55 -  69%    satisfactory (3)
70 -  84%    good (4)
85 -100%    excellent (5)

Exam: oral, student will draw two questions from the oral test lists. The midterm test result will take into account with 30%, and the oral exam with 70%.

Consultation: Consultation is possible in agreed time and place.
