1、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, liquid laser, semiconductor laser, solid laser, and solid laser which contains ruby laser, sapphire laser and YAG laser, YAG laser is a solid la
2、ser, it is different from ruby and sapphire laser, its 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：400600mj（毫焦），固定脉宽：10ns（纳秒），频率:110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, 400600mj, Fixed pulse: 10ns, Fr
3、equency: 1 10 times/secOut 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 preco
4、ndition 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 t
5、ime 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开关是一种带有时间控制的开关技术，开关一次能够把光的作用时间控制在10ns以内（1ns等于10亿分之1秒），这就是YAG激光的脉宽。Q-switching
6、is a time-controlled switch technology, switching to a role in the optical time in less than 10 ns (the output to 10 parts per billion an seconds), this is the YAG laser pulse. YAG激光可以产生1064nm、532nm两种不同波长的激光，1064nm波长的YAG激光对正常色素皮肤组织的穿透深度约为4mm，而532nm倍频YAG激光的穿透深度则较浅。YAG laser can produce 1,064 nm and 5
7、32nm two different wavelengths of laser, YAG laser of 1064nm wavelength on normal skin pigment of the penetration depth is about 4mm, and 532nm YAG laser frequency penetration depth is shallow. 两种不同波长的YAG激光对色素也有不同的选择，黑色和兰色对1064nm波长激光的吸收强于532nm波长激光，而红色和棕色对532nm波长激光的吸收又强于1064nm波长激光，因此1064nm波长激光选择破坏黑色和
8、兰色色素，532nm波长激光则选择破坏红色和棕色色素。Two different YAG laser wavelength of the pigment also have a different choice, black and blue wavelength of 1064 nm laser absorption is stronger than the 532nm wavelength laser, and the brown and red to 532nm wavelength laser absorption is stronger than the 1064 nm wavele
9、ngth laser. So 1064 nm wavelength laser would damage black and blue pigment, 532nm wavelength laser is to undermine the Red and brown pigments. 不同的色素颗粒对不同波长激光的吸受系数不同，而且不同波长的激光对不同色素颗粒的穿透深度也不同。黑色和兰色色素颗粒对1064nm波长的激光的吸收能力强于532nm波长的激光，而红色和棕色的色素颗粒则相反。1064nm波长的激光对黑色和兰色皮肤组织的穿透深度约为1mm，532nm波长激光对红色和棕色的穿透深度仅为0
10、.3mm左右。Different pigment particles of different wavelength laser, absorption coefficient is different, and different wavelength of laser pigment particles of different depths of penetration is also different. Black and blue pigment granules on the 1064 nm wavelength laser absorption is stronger than
11、 the laser in the 532 nm wavelength, while red and brown pigment granules contrary. To black and blue skin, penetration depth of 1064nm wavelength laser is about 1mm, to red and brown skin, the penetration depth of 532nm laser wavelength is only about 0.3mm.

12、different pigment 1064 nm波长的激光可以破坏黑色和蓝色色素，可以用于洗眉、洗眼线（尤其对扩散的眼线效果更加神奇）、洗文身（黑、蓝）、外伤性色素、太田痣。 1064nm wavelength laser could damage the black and blue pigment, can be used for washing brow, eyeliner (especially for the pigment-proliferationeyeliner, could have magical effect), washing tattoo (black and bl
13、ue), traumatic pigment, naevus of Ota. 1064nm波长的激光祛除黑色唇线1064nm wavelength laser can eliminate black lip liner.1064nm波长的激光祛除黑色唇线1064nm wavelength laser can eliminate black lip liner. YAG激光不同光线破坏的色素Different YAG laser damage different pigment 532nm波长的激光可以破坏红色和棕色色素，可用于洗红唇、棕色文眉、祛除红血丝、鲜红斑痣（紫红色胎记）、颧部褐青色痣、
14、永久性祛除雀斑、蜘蛛痣。532nm wavelength laser could damage the red and brown pigments, and can be used for washing vermilion, brown eyebrow, eliminating Gongxiesi. PWS (purple Birthmark), the malar fuscoceruleus moles,freckles permanent- eliminated, spider angioma. YAG激光破坏色素的原理Principle of YAG laser pigment-da
15、maged 当相应波长、脉宽和能量的激光作用于色素颗粒时，瞬时的高温形成巨脉冲，被皮肤病变色素组织吸收后形成脉冲波，使色素颗粒气化、爆炸，此时部分浅表色素被击碎后呈粉末状弹出体外；When the corresponding wavelength, pulse and energy of laser have an effect on pigment particles, giant pulse from instantaneous temperature was formed, pulse wave was formed after skin lesions absorbed giant p
16、ulse,and pigment granules would gasification, explosion, At this moment , some superficial pigment were smashed to powder and was thrown out of our body. 较深部分被击碎的色素颗粒则被体内的巨噬细胞逐渐吞噬从而达到祛除皮肤色素的目的，其过程约需三个月左右。如还有残留色素，可在三个月后进行第二次，两次需间隔三个月以上。 Some were smashed deeper pigment granules were devoured by macrophage, thus we could achieve the objective of skin pi
