Description

波长可调谐激光装置
技术领域
本发明涉及一种使用波长可调谐激光的溶脂装置,更详细地,涉及使用由通过光参量振荡器生成各种波长的激光的激光装置所生成的各种波长的激光来根据部位或脂肪量适用不同波长的技术,尤其,涉及向各个光纤传输在上述激光装置中经调谐的激光波长。
背景技术
吸脂术(liposuction)是一种从人体脂肪层去除脂肪的技术。如上所述的吸脂术由于直接去除脂肪,与通过运动或饮食疗法去除脂肪相比,更易于去除需要快速去除脂肪的特定部位的脂肪。并且,由于运动或饮食疗法等是仅减少脂肪细胞大小的方法,因此除非脂肪细胞被完全去除,否则脂肪层将来会变得更厚,但是,在通过上述吸脂术进行手术的情况下,可从根本上减少脂肪细胞的数量,因此比运动或饮食疗法更容易去除脂肪。
如上所述的吸脂术一般通过在使用细管状的套管插入到脂肪层后沿着前后方向移动来分离及破坏脂肪细胞的方式吸脂。
为了上述方式的吸脂术的便利性,虽然已经研制出了振动式或超声波式吸脂装置等的技术,但仍存在需使用很多使用人员的力量的问题。
用于弥补上述问题的激光溶脂技术为利用激光能量破坏脂肪层的脂肪细胞的技术。被破坏的脂肪会通过淋巴系统自然排出到体外或通过吸入来进行去除。为向脂肪层传递激光能量,使用中空针或套管,而向上述中空针或套管传递激光能量时,还可使用光纤。与吸脂方式相比,上述激光溶脂方式具有显著的减少外伤及更大的脂肪去除效果,并且,激光脂肪分解对通过向脂肪层插入针头来对可能受损的小血管进行烧灼(cauterize)方面有效。并且,在如上所述的情况下,实际上可以使血液损失最小化。
在激光溶脂技术中,根据波长的不同,激光能量被脂肪吸收的程度也不同,所以可以通过选择性地使用波长来分解宽区或窄区和大量的脂肪量或少量的脂肪量。在现有技术中,为了选择多种波长,混合使用了各种波长的激光装置。在如上所述的情况下,存在为了选择性地溶解脂肪而需要设置多个激光装置的缺点。因此,在本发明中,对利用可从单一激光装置输出各种波长的波长可调谐激光来选择性地溶解脂肪的情况作记述。
为了在单一波长的激光中调谐各种波长,装置包括:泵浦光模块,用于生成单一波长激光束,以便进行泵浦;波长转换部,包括用于进行激光束波长转换的非线性光学介质;以及温度控制部,用于控制上述非线性光学介质的温度,以调节波长转换时的相位匹配角度。上述温度控制装置可以将非线性光学介质的温度保持在一定温度,以通过相位匹配来提高波长调谐效率。
若如上所述的波长可调谐激光使用适合相位匹配条件的非线性光学介质来在非线性光学介质中利用和频生成(SFG;sum frequency generation)、差频生成(DFG;difference frequency generation)以及光学参量生成(OPG;optical parametricgeneration)及光学参量放大(OPA;optical parametric amplification)方法,则可以将波长可调谐领域从紫外线区域扩展到红外线区域,而无需制造单独的谐振器。尤其,可以形成光参量振荡器(OPO;optical parametric oscillator)等的包括非线性光学介质的附加谐振器,来对在谐振器中通过光学参量效应生成的光进行谐振,从而可扩展波长调节范围。
在上述内容中所使用的非线性光学介质使用周期性化学计量的钽酸锂(Periodically Poled Stoichiometric Lithium Tantalate;PPSLT)、周期性极化镁掺杂铌酸锂(Periodically Poled Magnesium doped Lithium Niobate;PPMgLN)、周期性极化铌酸锂(Periodically Poled Lithium Niobate;PPLN)、周期性极化掺镁铌酸锂(Periodically Poled MgO-doped Lithium Niobate;PPMgOLN)、周期性极化化学计量铌酸锂(Periodically Poled Stoichiometric Lithium Niobate;PPsLN)、周期性极化钽酸锂(Periodically Poled Lithium Tantalate;PPLT)、周期性极化掺镁钽酸锂(PeriodicallyPoled MgO-doped Lithium Tantalate;PPMgOLT)、周期性极化化学计量钽酸锂(Periodically Poled Stoichiometric Lithium Tantalate;PPsLT)、周期性极化磷酸钛钾(Periodically Poled Potassium Titanyl Phosphate;PPKTP)等的具有准相位匹配(Quasi-Phase Matching;QPM)结构的铁电体波长转换材料。
与通过如上所述的光参量振荡器进行波长调谐的激光有关的现有技术在韩国专利申请第10-2005-0020648号及第10-2009-0125750号中已公开。

并且,本发明的目的为提供一种用于将波长可调谐激光传输到各个光纤的装置,即,使得在可调谐激光装置所生成的各种波长可以单独使用或同时使用。

通过波长调谐生成的激光中的一个通过滤波器109穿过,另一个激光通过滤波器109反射并被第三反射镜反射,由此向与穿过滤波器的激光相同的方向照射。上述2个激光波长分别通过光纤111a、111b传输,为了最终向组织内部传输,将传输到导管112a、112b。
在上述导管设置有快门作用的开关,从而可选择性地使用2个上述激光波长。
