About
This table enables to specify the parameters of the laser beam to be used in related calculations.
The laser beam is supposed to be gaussian or elliptic and is defined by its waist and M-square factors.
The waist is located at the center of the object surface and its half size in the related XZ and YZ planes are respectively defined by the parameters waistX and waistY.
The M-square factors in the XZ and YZ planes are respectively defined by the parameters M2X and M2Y. Obviously, the beam is gaussian when waistX is equal to waistY and M2X is equal to M2Y.
The power is defined in the power cell.
Note that "gaussian beam" is a language abuse when the M-square factor (in this case M2X and M2Y are identical, thus there is only one M-square factor), is strictly larger than "1". Indeed, in this case, the beam is not "fully" spatially coherent and is therefore different from the fundamental mode currently named "gaussian mode".
