Laser physics and nonlinear optics forms the cornerstone for many, diverse applications of optics in science and engineering. Students taking this course will carry out an optics oriented, experimental project allowing them to experience unique and direct exposure to cutting edge research in the fields of laser physics and nonlinear optics. Furthermore, students can expect to use state-of-the-art equipment, gain a working knowledge of conventional experimental techniques and hands-on skills in these fields. Such introduction should be an adequate preparation for working on a master assignment in the research laboratories of the Laser Physics & Nonlinear Optics group and the Optical Sciences group, as well as a variety of other groups that have their emphasis on optics or make use of optical methods in their research. Adequate literature will be provided, which introduces the student to theoretical concepts directly related to the topic of laboratory experiments and the employed instrumentation.
The main research themes in this course include frequency conversion and coherent spectral control, nonlinear optics, also at extreme intensities, and nonlinear interaction of radiation with free electrons. To drive such processes, laser sources operating over a wide range of light intensities and time scales are employed.
Examples of recent assignments are:
• Measuring femtosecond pulses with an autocorrelator and a Grenouille
• Measuring fluctuations in the high harmonic output generated from capillary waveguides
• Building a setup for stimulated Brillouin scattering in integrated waveguides
• Measuring the optical transfer function of reconfigurable microwave photonic devices in Si3N4 waveguide chips
• Building a setup for generating supercontinua in Si3N4 waveguides with a Ti:Sapphire ultra-short pulse laser
• Build a second harmonic generator based on Si3N4 integrated waveguides
• Measuring the spectrum of Kerr frequency combs generated in microring resonators
• Measurements and calculations on ring resonator mirrors
• Measuring the spectrum of ultra-narrow bandwidth hybrid diodelasers
Assessment
The assignment will be concluded with a report and a presentation.
