20912 Lasers: Principles and Applications
Credits: 4 advanced credits in Chemistry or in Physics
Prerequisites: 60 credits in the Sciences, including General Chemistry1 (or General Chemistry I + General Chemistry II), or Atoms, Molecules and the Properties of Matter 20201; Fundamentals of Physics (or Fundamentals of Physics I + Fundamentals of Physics II; or Mechanics + Electricity and Magnetism + Waves and Optics); Differential and Integral Calculus I (or Infinitesimal Calculus I); Quantum Theory I (or Quantum Mechanics and Atomic Structure or Modern Physics). Students must also fulfill all English requirements and take bibliographic instruction in the Library.
The course is based on chapters from Laser Chemistry: Spectroscopy, Dynamics and Applications, by H.H. Telle, A.G. Ureña, and R.J. Donovan (John Wiley & Sons, 2007). The materials include a study guide and a lab guide prepared by Igor Rahinov.
The aim of this course is to expose students to the basic principles of laser operation, and to a wide range of laser-based methods used in modern basic and applied research; To provide students with knowledge about laser-based techniques routinely used in spectroscopic analysis, molecular dynamics, photochemistry and photophysics, analytical, environmental and industrial applications.
Chapters: 1. Introduction; 2. Atoms and molecules, and their interaction with light waves; 3. The basics of lasers; 4. Laser systems; 5. General concepts of laser spectroscopy; 6. Absorption spectroscopy; 7. Laser-induced fluorescence spectroscopy; 8. Light scattering methods: Raman spectroscopy and other processes; 9. Ionization spectroscopy; 10. Reflection, refraction and diffraction; 11. Filters and thin-film coatings; 12. Optical fibres; 13. Analysis instrumentation and detectors; 14. Signal processing and data acquisition; 15. Photodissociation of diatomic molecules.
In addition, students study an advanced laser application, chosen by the course coordinator from among chapters 16-30 (e.g. intra- and bimolecular processes in the gas phase, cluster science and gas-surface interactions, environmental, analytical, industrial and bio-medical applications). The topic is announced before the beginning of the semester.
