The use of low-intensity lasers for biostimulation continues to produce controversies. This paper presents the basic principles of light propagation in tissue. Tissue properties such as fluorescence, absorption and scattering initiate a gradual loss of any "laser-specific" property of the light with distance from the irradiated surface. One of the aims of the discussion is to indicate if a given biological response is expected to be specifically dependent on a laser source, or if the same result also ought to be expected from more conventional light sources.
使用低强度激光进行生物刺激仍然存在争议。本文介绍了光在组织中传播的基本原理。诸如荧光、吸收和散射等组织特性会导致光的任何“激光特异性”特性随着与照射表面距离的增加而逐渐丧失。讨论的目的之一是指出给定的生物反应是否预期特别依赖于激光源，或者是否从更传统的光源也应该预期得到相同的结果。
