Rationale and Purpose of the Module:
This module develops the student's knowledge of atomic and molecular physics, particulary where these are relevant to spectra and laser physics. Based on this the module introduces the fundamentals of laser physics and laser applications including holography.
Syllabus:
Atomic structure: the hydrogen atom, energy level diagram and the origin of spectra, many-electron atoms, the influence of external fields, hyperfine structure, isotopic shifts, the shell model, X-ray spectra.
Molecules: diatomic molecules, vibrational and rotational states, complex molecules, vibrational modes.
Molecular emission and absorption spectra in the visible and infrared.
Fundamentals of laser action: cavities, laser media, gain, losses, cavity linewidths, broadening mechanisms.
Spatial and temporal properties: Gaussian beams, cavity modes, mode locking and Q switching, solid state lasers.
Laser Applications: industrial, medical, data storage, holography and holographic techniques, laser safety.
Learning Outcomes:
Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)
On successful completion of this module, students should be able to:
- Define the key concepts in atomic, molecular and laser physics.
- Explain, on the basis of quantum mechanics, the origin of the features of atomic and molecular emission and absorption spectra in all wavelength ranges.
- Apply appropriate models and approximations to derive relationships between physical variables which may be measured experimentally.
- Apply the principles of modern physics and optics to predicting, describing and explaining the operation and characteristics of lasers..
- Solve problems, from information given, requiring the calculation of the values of physical variables in atomic, molecular and laser physics.
Affective (Attitudes and Values)
- Discuss the relevance of atomic and molecular spectra in modern applied physics and chemistry.
- Explain the importance of lasers in modern technology.
Psychomotor (Physical Skills)
- Perform experiments requiring precise measurement
- Use electronic and optical apparatus for observation and measurement.
How the Module will be Taught and what will be the Learning Experiences of the Students:
Students will learn via interactive lecture, laboratory, experiential and interactive tutorial, and problem-based private study.
