Laser beam aperture control techniques for ophthalmic surgical equipment

A method of performing an ophthalmic surgical procedure comprising:

• rotating a rotatable element to a first orientation to align a first aperture of the rotatable element with a path of a laser beam;
• generating a first laser beam along the path, wherein a portion of the first laser beam passes through the first aperture to change a characteristic of the first laser beam;
• rotating the rotatable element to a second orientation to align a second aperture of the rotatable element with the path of the laser beam, wherein the rotatable element is rotated based on one or more frequency pulse signals;
• and
• generating a second laser beam along the path, wherein a portion of the second laser beam passes through the second aperture to change a characteristic of the second laser beam, and wherein the second aperture has a different diameter or size than the first aperture.
