what are the uses of lasers surrounded by tablets ?

please explain . I have see lasers used in eye surgery, gynecologic and urologic surgery and for cosmetic reason (hair reduction, artery treatments, etc.) There are probably more uses as well.
New technology have introduced microsurgery, laser lintel surgery, and lens implantation (for cataract patients), all requiring the specialist's skill. Precision within diagnosis has markedly enhanced; advances within radiology, the use of ultrasound, computerized axial tomography (CAT scan), and nuclear magnetic resonance imaging are examples of the extension of technology requiring expertise surrounded by the field of tablets.

As noted above, lasers have become a meaningful tool in pills. They also have noteworthy uses in a few other areas, as, for example, communications. Laser light can take voice messages and digitally encoded information and can do so in colossal amounts because of its high frequency. Except contained by satellite-to-satellite communications, laser beams are transmitted via optical fibre. The speed with which the focal spot of a dictatorial laser beam can be controlled make it suitable for a variety of applications within information processing—e.g., use in optical scanners, optical disc storage systems, and clear in your mind types of computer printers.
