We look at pump probe methods using ultrafast pulses for high temporal resolution experiments.
Short Pulse Generation
We look at transient effects in laser gain material, -switching and mode locking as methods to get short pulses.
Raman Scattering
Podcsat from 2008 of lecture on Raman spectroscopy. This is in place of the 11/9 lecture given about Raman spectroscopy, for which the audio...
Stimulated Raman Spectroscopy
Podcsat from 2008 of lecture on stimulated Raman scattering. This content was not covered in class this semester. This is for your interest...
Nonlinear Spectroscopy
We look at how saturation causes hole burning in a spectral line, and measurement techniques such as lamb-dip spectroscopy and intermodulate...
Emission Spectroscopy
We look at basic methods of emission spectroscopy including laser induced fluorescence, resonant enhanced multi-photon emission (REMPI), int...
Absorption Spectroscopy
WE look at basic techniques of absorption spectroscopy including direct detection, frequency modulation, intracavity absorption and cavity r...
spectral line profiles
We look at how the natural lifetime of an energy level produces a Lorentzian line profile and how the natural linewidth can be broadened by...
Interferometers
We look at how interferometers can be used to measure wanelength.
Spectrometer Operation
We look at the principles of operation of prism spectrometers and grating spectrometers and discuss operating characteristics (speed, resolv...
Photodetectors
We consider the advantages and disadvantages of three classes of photodetectors: photodiodes, photomultiplier tubes and thermal detectors.
Tunable Lasers
We look at several examples of tunable lasers and discuss nonlinear optics as a mechanism to increase the region of the spectrum available f...
Fundamentals of Lasers
We look at 3-level and 4-level gain systems in laser amplifiers, discuss optical cavities and tuning elements of laser oscillators.
Molecular Absorption
We look at an example of calculating the bond length and bond strength of HCl from a measured mid IR absorption spectrum.
Molecular Energy Levels
We look at energy levels associated with rotation and vibration of molecular bonds
Energy Levels
We look at the Bohr model of the atom and see how it can be used to explain the line spectrum of Hydrogen, and then generalize to other atom...
Gravity Measurements
We look at an application of our previous quantum treatment of the two-level atom for measuring G the universal gravitational constant.
Quantum Model of Absorption
We look at absorption as a quantum effect and introduce the Einstein A and B coefficients for stimulated and spontaneous emission.
Index of Refraction and Absorption
We use the classical electron oscillator model to derive the functional form of the index of refraction in material as well as the absorptio...
