Studies of laboratory animal retinal exposure to green monochromatic laser radiation show an increasing stability of tissue with increasing pulse duration up to 10(-1) s. This mechanism of biological response of the eye to light damage is fundamental to living systems. It does not manifest itself in animals under deep anesthesia. A mathematical model has been developed which permits one to predict the dependence of threshold injury of visible monochromatic radiation. The model is based on the assumption that the entropy of the reaction of thermal tissue denaturation decreases with increasing pulse duration. This may be used to refine safety standards for personnel working with lasers and to optimize the parameters of lasers used in ophthalmic surgery.
对实验动物视网膜暴露于绿色单色激光辐射的研究表明，随着脉冲持续时间增加至10⁻¹秒，组织的稳定性不断增强。眼睛对光损伤的这种生物反应机制是生命系统的基础。在深度麻醉的动物身上不会表现出来。已经开发出一种数学模型，可用于预测可见单色辐射的阈值损伤依赖性。该模型基于这样的假设：热组织变性反应的熵随脉冲持续时间增加而降低。这可用于完善激光操作人员的安全标准，并优化眼科手术中使用的激光参数。
