Sitting at the dinner table with his family on Thanksgiving in 1981, Srinivasan looked at his turkey dinner and a brilliant thought occurred to him: a leftover bone with cartilage would provide the perfect test subject. The cartilage and other tissues attached to the turkey bone could approximate the physical structure of human tissue, and the smoothness and rigidity of the cartilage would make it easier to read the results of the experiment. On November 27, 1981, the team operated an argon fluoride (ArF) excimer laser to create a clean etching on the turkey’s cartilage that could be viewed when placed under an optical microscope. Further tests on the cartilage helped the team understand how many laser pulses were required to make a cut, the amount of energy delivered via the laser beam and the impacts of the laser on adjacent tissues.
