Burcu Tunc et al.
Lasers in surgery and medicine, 45(1), 48-56 (2013-01-17)
The thermal damage of the surrounding tissue can be an unwanted result of continuous-wave laser irradiations. In order to propose an effective alternative to conventional surgical techniques, photothermal damage must be taken under control by a detailed dose study. Real-time
