Relations:

In order to register for the course 12ZPLT, the student must have successfully completed in previous semesters the required number of courses in the group 12ULT.

Course guarantor:

Václav Kubeček

Lecturer:

Josef Blažej, Václav Kubeček

Tutor:

Josef Blažej, Milan Frank, Kryštof Kadlec, Jan Kratochvíl, Jan Olšan, Matěj Stavinoha

Supervisor:

Department of Laser Physics and Photonics

Synopsis:

Lasers, solid state Nd:YAG laser, laser crystal, laser discharge lamp, laser cavity, resonator, free-running, Q-switching, laser amplifier. second harmonic, He-Ne glow discharges, laser diode, diode pumped Nd:YAG laser, CO2 laser marking, laser materials properties, non-linear transmission, laser beam transverse profile, acousto-optic modulators.

Requirements:

Personal attendance in the practical training is mandatory. Students measure individually or in groups, depending on the number of students in a given semester. The time and group distribution is determined by the subject guarantor. The timetable includes at least one spare measurement date.

Students prepare a protocol for each measurement, which they submit electronically no later than the next measurement or within one week after the last measurement. Who prepares the protocol for the group is up to the internal arrangement of the group.

Obviously incorrect protocols will be returned immediately for revision. An unsubmitted protocol is graded F. All protocols are graded collectively until the end of the regular examination period.

If at the end of the semester any of the protocols is graded F, the final grade for the course is F. Otherwise, the final grade is given by the arithmetic average of the grades of all partial protocols.
