什么是YAG激光

什么是YAG 激光 What is YAG laser? 激光的种类很多，有气体激光、液体激光、半导体激光、和固体激光，其中固体激光包含红宝石激光、蓝宝石激光和 YAG 激光等，YAG 激光属于固体激光的一种，它不同于红宝石和蓝宝石激光它的发光晶体是石榴石。 Laser has many kinds; gas laser, liqu id laser, semicondu ctor laser, solid laser, and solid laser which contains ruby laser, sapphire laser and YAG laser, YAG laser is a solid laser, it is different from ruby and sapphire laser, it’s luminous is crystal garnet. YAG 激光的主要参数 YAG laser parameters YAG 激光的主要参数为波长：1064nm/532nm（纳米），输出能量：400～600mj（毫焦），固定脉宽：＜10ns（纳秒），频率:1～10 次/秒。 除了以上参数外 YAG 激光还采用了调 Q 开关技术。 YAG laser wavelength of the main parameters: 1064nm/532nm, 400～600mj, Fixed pulse: ＜10ns, Frequency: 1 ~ 10 times/sec Ou t of these parameters, YAG laser was also adopted Q-switched technology. 为什么采用调 Q 开关技术 Why do we use Q-switched technology? 祛除皮肤色素是以不损伤皮肤为前提的，除了选择激光的波长、输出能量、频率等指标外，还要保证不在正常组织上产生热量积累。既要有足够的能量击碎色素颗粒，又不让能量产生的时间过长，而损伤细胞组织。为此 YAG 激光采用了先进的调 Q 开关技术，把激光的固定脉宽控制在 10ns(1ns 等于 10 亿分之 1 秒)以内。 The precondition of skin pigment elimination is not to injure skin. Except for the selection of laser wavelengths and energy output, frequency and other indicators, but also guarantee that it will not have a normal heat accumulation. Both have enough energy smashed the pigment particles and energy from the time is too long and tissue injury. YAG laser use the advanced Q-switched technology, the fixed laser pulse control within 10 ns (the output equivalent to a 1 billion per seconds) 什么是调 Q 开关技术 What is the Q-switch technology? 调 Q ...
