激光特性参数与激光生物效应

The Relation between the Characteristic Parameter of Laser and the Effect of Laser Biology

本文从国内近年来开展的多种激光生物效应实践出发,探讨激光特性参数对激光生物效应的影响。文中指出不同波长激光可对同一生物体产生同一类型变异,不同种类生物体对应最佳波长、最佳剂量不同。低剂量激光对众多生物体产生有效刺激效应。在低功率激光生物效应中空间相干性起主要作用。非偏振激光可获有效生物效应。文中还对某些实验现象作了解释。

Based on the experiments of laser biological effect in China, the relation between the characteristic paramete of laser and laser biological effect is discussed. The optimum wavele gth and irradiation dose are existed. The low irradiation dose can cause effective effect. The sp:tial coherence plays an important role in the experiment. The nonpolarized laser can cause an obvious effect. Some experimental phenomena are explained in this paper,
