The question of lasers' exclusivity, as well as the degree of influence of special properties of low-intensity laser illumination (LILI), such as coherence, polarity and monochromaticity, on the effectiveness of low level laser therapy (LLLT) continues to cause arguments. The study analyzes publications from 1973 to 2016, in which laser and conventional light sources are compared, and the following conclusions are drawn. First, there are a lot of publications with incorrect comparison or unfounded statements. Secondly, other sources of light are often meant by LILI without any justification. Thirdly, all studies, in which the comparison is carried out correctly and close parameters of the impact and the model are used, have a firm conclusion that laser light is much more effective. Fourthly, it is uniquely identified that the most important parameter that determines the efficiency of lasers is monochromaticity, i.e., a much narrower spectral width than for all other light sources. Only laser light sources can be used for LLLT!
激光的独特性问题，以及低强度激光照射（LILI）的特殊性质（如相干性、偏振性和单色性）对低水平激光疗法（LLLT）有效性的影响程度，一直存在争议。该研究分析了1973年至2016年期间的出版物，其中对激光和传统光源进行了比较，并得出以下结论。首先，有许多出版物存在不正确的比较或毫无根据的陈述。其次，LILI常常被无端地理解为其他光源。第三，所有进行了正确比较并使用了相近的影响参数和模型的研究都得出了一个确凿的结论，即激光更有效。第四，明确指出决定激光效率的最重要参数是单色性，即其光谱宽度比所有其他光源都窄得多。只有激光光源可用于LLLT！
