Wavelength: wavelength of the laser in meters.

Delete Laser Button: Deletes the current laser (as shown in the drop down menu).

Save Laser Button: Saves current values of the edit boxes.

New Laser Button: Clears the edit boxes widths and divergence angles derived from the second moments of the power (energy) density distribution function allow calculation of beam propagation.

Y direction is perpendicular to the junction d of the wave beam and its angular divergence Y can be measured in the symmetry plane z of the waist 14✡6 (Fig.

X direction is parallel to the junction.

when you change any Y value the other three Y values are re-calculated to match your input.

when you change any X value the other three X values are re-calculated to match your input.

when you change the wavelength all values are recalculated assuming that the near-field spot fwhm is constant.

The Laser Diode Calculator can be accessed through the Accessories menu or from the Custom Pattern Panel. The beam parameter product is a physical parameter which describes the beam quality, and hence the focusability, of a laser beam.

The custom pattern generator can then be used to generate a realistic laser diode source. Contains specifications of several commercial lasers and allows the user to calculate far field divergence angles and near field spot size values for typical laser diodes One of the main uses of this calculator is to lookup or calculate values to use in the custom pattern generator since most laser diode specifications list far field divergence in degrees while Optiscan works with the spot size in meters.
