Paper Abstract

The laser blood sampling is the last idea. The idea is based on focus laser beam to pierce the finger skin, and then we can get and analyze the blood sampling. Because there is not contact the method can wholly avoid the contact infection. In the paper, the core light source is a compact no water-cooled Er-doped YAG solid laser, researched and developed by ourselves. The erbium laser output wavelength is 2.94?m, which is accordance with water' s absorption peak. The water' s absorption in tissues is particularly great, so the erbium laser is suitable. Simultaneously we design the laser alignment system, the laser shaping system and the focal setting system. Depend on the theoretical analysis and experiments, we research and develop a medical blood—sampling instrument of laser, with the good application prospect.
