Outline:

This module gives a thorough introduction to laser physics, optics and nonlinear optics.

Aims:

To provide a useful and exciting module on lasers and modern (nonlinear) optics, with insight into non-linear processes and modern applications of lasers.

Intended Learning Outcomes:

At the end of the module students should be fully conversant with the physical principles of laser action, the optics of laser resonators, the propagation of laser beams and the nonlinear interaction of laser radiation with matter (nonlinear optics). Students should be competent in applying this knowledge to problem solving in these areas.

Teaching and Learning Methodology:

This course is delivered via weekly lectures supplemented by a series of workshops and additional discussion.During the course there will be an opportunity to tour the Department’s extensive laser facilities.ÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌýÌý

In addition to timetabled lectures, it is expected that students engage in self-study in order to master the material. This can take the form, for example, of practicing example questions and further reading in textbooks and online.

Indicative Topics:

Physics of optical transitions, Population inversion and gain in 3 and 4 level lasers, Resonator theory: longitudinal and transverse modes, resonator stability, ray optics, Laser Q Switching, Laser Modelocking, 2nd Order Nonlinear Optics-Second Harmonic Generation, birefringence and quasi phase matching, 3rd Order Nonlinear Optics -Intensity dependent refractive index and Kerr Lens Modelocking, self phase modulation, chirping and laser pulse compression.
