Medical Lasers Cut and Heal

Photonics Spectra
Dec 2016
New innovations in medical lasers allow for greater control of wavelength, power and pulse duration, expanding applications beyond ablation and tissue removal to include bioresponse and drug delivery.

HANK HOGAN, CONTRIBUTING EDITOR, hank.hogan@photonics.com

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 an ushering in of an additive approach. The key for either subtraction, addition or a combination is to get the right wavelength at the right

GLOSSARY
biostimulation
The action of a biological system responding to a single or multiple coherent particles of light produced from a laser source. Examples of laser biostimulation include: retinal interaction of light emission with rhodopsin, photosynthesis, and photodynamic therapy
