10 Tips White Paper 1 rev9

…3 Improve the effectiveness of your process. Expanding, contracting or focusing a laser beam changes its power density, but not its total power. And, in most applications, the power density determines the precise nature and effectiveness of the laser process. 4 Understand the dynamics of your laser.…

…all possible factors that might affect
it. Furthermore, it's ultimately desirable to develop a rapid measurement method, so that power
density and beam waist location could be measured between each layer write cycle, without
significantly slowing deposition down. This would enable any…

…beyond just the laser power or power density.
In many applications, it is required to focus the laser beam in order to create very small spot sizes and, hence, to
increase power density or brightness. For a given output power, the power density can be increased by reducing the
