Laser Data |
|
|
| Peter and Ryan took laser beam data. Configuration: 100mm focal length lens is ~100mm from lens. 150mm focal length lens is ~200mm from first lens. Beam waist is ~420mm from second lens.
Beam waist is very small still. Had to input large amounts of error in data collection. Took width data successively at points near waist and at >= Rayleigh range. Plots are shown below.
Key points:
Took a while to figure out optimum configuration for lenses to be placed so that an accessible beam waist could be obtained.
Beam waist is still very small. May need to do an ABCD calculation to see if there is anything bigger that can be obtained. |
