Abstract

The impact of visible cwlaser irradiation on skin autofluorescence lifetimes was investigated in spectral range from 450 nm to 600 nm. Skin optical provocations were performed during 1 min by 405 nm low power cw laser with power density up to 20 mW/cm2. Autofluorescence lifetimes were measured before and immediately after the optical provocation.
荧光寿命光谱:低功率激光治疗后皮肤荧光团变化体内估计的潜力
在450 ~ 600 nm光谱范围内研究了可见光激光照射对皮肤自身荧光寿命的影响。使用功率密度高达20 mW/cm2的405 nm低功率连续波激光器,在1分钟内对皮肤进行光学刺激。在光学激发之前和之后立即测量自身荧光寿命。
