Laser frequency stabilization
We look at sources of laser frequency noise and discuss feedback techniques using a reference cavity or a molecular transition to stabilize the laser ...

About
Lecture recordings from Physics 268 at San Jose State University. 75 minute enhanced audio epsiodes will be added on Monday and Wednesday nights throughout Fall of 2009.
Ultrafast Spectroscopy
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 didn't re...
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 only and w...
Nonlinear Spectroscopy
We look at how saturation causes hole burning in a spectral line, and measurement techniques such as lamb-dip spectroscopy and intermodulated fluoresc...
Emission Spectroscopy
We look at basic methods of emission spectroscopy including laser induced fluorescence, resonant enhanced multi-photon emission (REMPI), intermodulate...
Absorption Spectroscopy
WE look at basic techniques of absorption spectroscopy including direct detection, frequency modulation, intracavity absorption and cavity ringdown sp...
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 Doppler br...
