Systems and method for optimization of laser beam spatial intensity profile

An apparatus comprising:

• a laser generation module adapted to generate a laser beam;
• beam shaping optics adapted to shape the intensity profile of the laser beam in at least the short axis of the beam;
• a stage configured to support a target film;
• a translator coupled with the stage, the translator adapted to translate the film in a first direction in a number of discrete steps, wherein each of step is governed by a predetermined step size;
• and
• an optimization tool coupled with the laser generation module, the optimization tool adapted to select between a high energy mode and a low energy mode.

A computer-readable medium containing instructions which, when executed by a computer, perform a process comprising:

• selecting a high energy mode or a low energy mode for a laser beam to be generated at a laser generation module;
• generating the laser beam at the laser generation module according to the selected mode;
• adjusting beam shaping optics to shape of the intensity profile of the laser beam in at least the short axis of the beam;
• translating a target film in steps, where each step is governed by a predetermined step size;
• and
• reselecting an energy mode after translating the film a predetermined number of steps.
