Advanced Laser Systems and Technology 7.5 credits

About the course

After a repetition of the basics of laser action, the course covers different types of continuous wave and pulsed lasers (especially semiconductor, fibre lasers, and solid-state lasers) operating in a wide range of wavelengths (from the X-ray region through, the visible, and up to the mid-infrared range) with a variety of properties (everything from an extremely narrow linewidth, via multimode behaviour and frequency comb structure, to broadband ultra-short high-power pulses). Methods for controlling the laser mode structure, linewidth, frequency, temporal structure, and polarisation are discussed. Techniques for nonlinear frequency conversion - including frequency doubling, sum- and difference-frequency generation, and optical parametric processes -light amplification and supercontinuum generation are treated. The course also includes a treatment of equipment and techniques for active control of light, e.g., frequency control, active and passive mode-locking, and chirped-pulse amplification using electro- and acousto-optical modulators and Faraday isolators. Finally, other advanced light sources, such as attosecond sources based on high harmonic generation, synchrotrons, and free electron lasers are discussed. The course comprises a theoretical module of 6.0 credits, and a laboratory module of 1.5 credits.
