    • A laser apparatus for medical treatment use in which a laser beam is irradiated on a portion of a human body to be treated comprises a laser beam generation unit for generating a laser beam of giant pulse, a laser beam guide member having one end through which the laser beam from the laser beam generation unit is guided, and a hand piece attached to another end of the laser beam guide member and irradiating the laser beam to the portion to be treated. A beam converging point is formed within a laser beam propagating path formed in at least one of the light guiding means and the hand piece and a stay of air is prevented from a predetermined region in the laser beam propagating path including at least the beam converging point at which the air stays. The predetermined region is positioned within the hand piece or the laser beam guide member. The air stay is prevented by means of producing a vacuum state, gas seal state or air flow state in the predetermined region.
    • 用于医疗的激光装置,其中激光束被照射在待处理的人体的一部分上,包括用于产生巨脉冲激光束的激光束产生单元,具有一端的激光束引导构件, 来自激光束产生单元的激光束被引导,并且附接到激光束引导构件的另一端并将激光束照射到待处理部分的手部件。 在形成在至少一个导光装置和手持件中的激光束传播路径内形成束会聚点,并且防止空气滞留在至少包括光束会聚点的激光传播路径中的预定区域 在那里空气停留。 预定区域位于手持件或激光束引导构件内。 通过在预定区域中产生真空状态,气体密封状态或空气流动状态来防止空气滞留。
