Several types of lasers have been used as surgical tools to incise or excise tissues without causing bleeding. For example, CO<SUB>2</SUB> lasers are one of the most commonly used lasers in surgeries. They can effectively ablate tissues because the emitted light is efficiently absorbed by water molecules. AlGaAs and InGaAs laser diodes, which emit near infrared light, are preferable for hemostasis because near infrared light penetrates deeply into tissues and results in a thick coagulation layer. The 405-nm GaN laser diode is a newly developed laser that has recently been studied as a potential surgical tool. The emitted light is efficiently absorbed by proteins, such as hemoglobin, and melanin pigments. Due to these absorption characteristics, we expected the 405-nm laser diode to cut tissues effectively. In this study, irradiation of rat tongues and samples of tuna confirmed that the 405-nm laser diode can be used to effectively perform bloodless surgeries.
