What components are found in articulated arms used in some laser delivery systems?

Articulated arms in laser delivery systems utilize mirrors as a crucial component to direct and manipulate the laser beam. The mirrors are strategically positioned within the arm to ensure that the laser can be precisely aimed at the intended target, especially in applications where the path of the laser needs to be altered, such as in surgical procedures or aesthetic treatments. The ability to bend and reposition the articulated arm allows for greater versatility and precision in laser delivery.

While optical fibers are important in some laser systems for transmitting light, they do not apply specifically to articulated arms as a primary component. Cooling fans and power generators may be necessary for the overall functionality of a laser system, but they do not play a direct role in the mechanics of an articulated arm's design or operation. Therefore, mirrors are the correct choice as they serve the essential purpose of reflecting and guiding the laser light through the articulated arm.
