Gaussian Beam Propagation

Measurement method:

Data from one blade scan: accept this data
Radial position of spot on chopper wheel
Number of chopper teeth on wheel
Diameter of pinhole
Period of square wave
risetime measured from % to %
treat wavelength as unknown

Units for data:

[distance from laser: [position in ] [blade transverse position in ] [rise time in ] [pulselength in ] [radius in ]
Beam parameters from curve fit:
