    • It is possible to provide a laser unit which can sting a skin with a small-diameter hole causing a small pain. The laser unit (1) includes: a laser rod (3) which applies a laser beam; a lens (7) which collects a laser beam applied from an irradiation unit; and a laser transmission plate (9) having a mirror portion on the side to which the laser beam comes in and a rough portion having an average surface roughness Ra on the side from which the laser beam goes out. With this configuration, the laser beam which has passed through the laser transmission plate (9) is scattered by the rough portion and the intensity of the laser beam applied to the skin is not concentrated to the center. Moreover, the laser beam generates an impulse wave when passing through the rough portion. That is, the energy is discharged in advance.
    • 可以提供一种激光单元,该激光单元可以用引起小疼痛的小直径孔刺伤皮肤。 激光单元(1)包括:施加激光束的激光棒(3) 收集从照射单元施加的激光束的透镜(7) 以及在激光束入射的一侧具有反射镜部分的激光透射板(9),以及激光束出射侧具有平均表面粗糙度Ra的粗糙部分。 利用这种结构,通过激光透射板(9)的激光束被粗糙部分散射,并且施加到皮肤的激光束的强度没有集中到中心。 此外,当穿过粗糙部分时,激光束产生脉冲波。 也就是说,能量提前释放。
