Innovations expand applications beyond ablation and tissue removal to include bioresponse and drug delivery.

HANK HOGAN, CONTRIBUTING EDITOR, [email protected]

For medical lasers, the future may include both addition and subtraction. That’s because in medicine, lasers have traditionally been used for ablation, cutting and other processes that remove tissue. Now researchers and companies are looking into harnessing the power of light to stimulate a bioresponse, thereby triggering growth and ushering in an additive approach. The key for either subtraction, addition or a combination is to get the right wavelength to the right spot at the right intensity and duration. Beyond that, systems have to allow a fast learning curve so that...Read full article
