In 1981, Srinivasan discovered that an ultraviolet excimer laser can be pulsed at 193 nm to etch a living tissue precisely without causing any thermal damage to surrounding area.
In 1981, Srinivasan and his coworkers determined that an ultraviolet excimer laser could be used to etch designs into polymers. An ultraviolet excimer laser pulsed at 193 nm was able to etch living tissue precisely without causing any thermal damage to surrounding area.
