High-power level lasers used in health sciences have important photothermal effect. The maximum absorption of the diode laser correlates with the absorption range of hemoglobin, suggesting that red color may be the required chromophore. Hence, we hypothesized that by providing artificial external red chromophore, we can improve the cutting efficiency of diode laser in noninflamed tissue. The aim of the present study was to assess the efficacy and collateral thermal damage produced by a 940 nm diode laser on stained and unstained porcine tissue sample.
