Movies from Trebino on group velocity: Vg = Vp Vg > Vp Vg < Vp
Also, see the applet "subluminal" below to test your
understanding. It illustrates Vg > c.
| Fourier Synthesis | Mostly for your amusement. Uses your speakers so you can hear the result. |
| Fourier Synthesis | Another one with sound. See if you can "modelock". |
| Fermat's Principle | Illustrated for reflection and refraction. |
| Group velocity and phase velocity | Simple illustration of how a wave looks when differing speeds are used. Try it at the highest frequency and follow the motion near the node in the envelope function. |
| Simple group velocity demonstration | Simple illustration based on the superposition of two waves. |
| Group Velocity Demonstration | Allows you to superpose two arbitrary waves specified using C-like syntax. |
| Subluminal | Illustrates how a pulse can appear to propagate faster than light. (The author should have named it "superluminal" I suppose.) |
| Gaussian Modes Illustrated | Computer generated idealized case, as opposed to the handout I gave you. |
| TEM00 mode | It's hard to focus your eyes on a true TEM00 Gaussian mode. |
| Stability Diagram of an Optical Cavity | Shows your location in the diagram as you modify cavity parameters. Includes a model of the laser cavity below the diagram. |
| Rays Trajectories in an Optical Cavity | Ray trace analysis of a two mirror cavity with adjustable parameters. |
| Cavity Mode | Better version of the above. Find a configuration that gives you a large mode everywhere. Try other variations. |
| Laser dynamics | You select the pump/loss/decay parameters and it solves the rate equations. Excellent for understanding self-Q-switching, transient response, and the approach to steady-state. |
