The safety of the application of the Nd:YAG laser for hemostasis in emergency gastro‐endoscopy when its irradiation is properly dosed is demonstrated on the basis of laboratory investigations as well as theoretical calculations on a mathematical model of internal scattering. The increased effectiveness of this laser compared with argon and CO 2 lasers in producing in‐depth volume heating is shown to derive from the fortuitous combination of its low absorptivity with the scattering phenomenon.
