Description The purpose of this module is to give students a working knowledge of (1) the theory and operation of lasers and (2) some optical phenomena related to and made possible by laser radiation. In particular, non-linear optical effects and effects employed in the modulation of optical radiation are treated. | |||||||||||||||||||||||||||||||||||||||||
Learning Outcomes 1. Outline the fundamentals of the electromagnetic optics of crystals and non linear media 2. Explain the theory of the optical oscillator to include resonator optics and the physics of the laser amplifier with selected examples of gas and solid state lasers. 3. Describe the principles of pulsed laser operation to include Q-switching (ns lasers), mode-locking (ps lasers) and pulse chirped amplification (fs lasers) 4. Outline the principles of Electro-optics to include laser based applications 5. Outline the principles of second- and third-order Non linear optics to include laser based applications 6. Describe and explain in detail a state of the art development in the field of photonics | |||||||||||||||||||||||||||||||||||||||||
