as scalpels in surgical procedures

Explanation:

There are many different types of lasers with many different types of applications. High-frequency, high-energy lasers are able to very precisely cut various objects. Such lasers are often used as scalpels in surgical procedures.

The frequency of light that a laser emits can made high enough to delicately cut human or animal tissue. Such lasers are often used in different types of eye surgery, brain surgery, and vascular surgery. Some lasers emit light of even higher frequencies and are often used in industrial applications to cut metals and other materials.

it takes hundreds of years to become stable.
