但随着输出功率的进一步提高，人们越来越发现保障人眼安全问题成为光纤激光器发展的重要问题。

由于掺铥光纤激光器的发射波长在2 μm附近，属于人眼安全波段范围，所以掺铥光纤近几年发展迅速，成为研究热点。

铥，为镧系稀土元素，原子序数69。

光纤激光器的发射波长在2 μm附近，能够实现1.6～2.1 μm的调谐，是所有稀土离子中最宽的，其中2 μm近红外长波段对人眼安全，保护视网膜不会受到高功率激光的照射，避免引发永久伤害和失去视力，可广泛应用于激光雷达、遥感技术以及激光医学、眼睛安全的近距离遥感、军事等领域。

这种波段的激光在普通石英光纤中表现出良好的传输特性（＜0.44 dB/m），而且由于铥离子特殊的能级结构，不同能级之间的交叉驰豫可突破理论的Stokes效率极限，大大提高激光器的效率，离子效率理论值可高达2，而且利用频率上转换技术（Frequency Upconvertion）产生可见光，可使近红外光泵浦的光纤成为可见荧光辐射源和激光辐射源，在光纤陀螺、光学测量诊断技术、分子生物学、医学等方面具有重要的应用价值。

由于掺铥光纤激光器具有重要的应用价值，国外在掺铥光纤激光器的研究方面发展迅速。

【正文：】激光有着良好的相干性（空间相干），并且能够提供很高的脉冲峰值功率，故而在目前，激光的应用范围十分的广泛。

许多情况下，尤其是制造业，在切割、焊接、钻孔等方面，高度稳定的能量是必不可少的。

低功率光纤放大器是光纤网络的重要组成部分，同时它也可以发展成为工业用激光器的领跑者。

目前它的输出功率已经达到1kw，最近更是达到了惊人的10kw以上。

而这些成果都受到衍射受限光束的光束质量的限制，因为这一属性决定了光束是否能够有效地汇聚于一点。

连同强度和波长,它们一起决定了空间光的亮度和辐射率。

激光的高亮度并不取决于激光本身的能量大小，而取决于光纤激光器能够照射到目标上的能量密度。

大功率光纤激光器的成功背后有几个小秘密。

一个是包层泵浦【cladding-pumping】(4 - 6)，与传统的光学纤维(见图)相比，它使用更为复杂的光纤结构。

除了用通常的纳米数量级纤芯的光纤【few-micrometer-sized】来导光，这种双层包层的光纤还包括一个二级的同轴波导包围着纤芯。

大多数光纤激光器的光泵浦都采用半导体激光二极管，这种体积较大的二级同轴波导则在空间上容许更多的激光半导体二极管来作为泵浦，用以提供几千瓦的低成本、低亮度的光功率。

其后我们向纤芯中掺杂了镱【Ytterbium】，作为激光激活（放大）的掺杂剂。

镱是一种十分有效的激光放大离子，一方面是由于放大光的波长(1040nm——1100nm)与泵浦光的波长(910nm——980nm)十分接近(7、8)。

而两者不同之处则被称为“量子数亏损”，量子数亏损决定了激光器所产生的散热，为了降低发热，可以证明，波长为1020nm的泵浦光适用于10kW的激光器(3)。

光纤激光器与光纤激光器技术光纤激光器是指用掺稀土元素玻璃光纤作为增益介质的激光器，光纤激光器可在光纤放大器的基础上开发出来：在泵浦光的作用下光纤内极易形成高功率密度，造成激光工作物质的激光能级“粒子数反转”，当适当加入正反馈回路（构成谐振腔）便可形成激光振荡输出。

光纤激光器应用范围非常广泛，包括激光光纤通讯、激光空间远距通讯、工业造船、汽车制造、激光雕刻激光打标激光切割、印刷制辊、金属非金属钻孔/切割/焊接（铜焊、淬水、包层以及深度焊接）、军事国防安全、医疗器械仪器设备、大型基础建设等等。

光纤激光器的优势光纤激光器作为第三代激光技术的代表，具有以下优势：（1）玻璃光纤制造成本低、技术成熟及其光纤的可饶性所带来的小型化、集约化优势；（2）玻璃光纤对入射泵浦光不需要像晶体那样的严格的相位匹配，这是由于玻璃基质Stark 分裂引起的非均匀展宽造成吸收带较宽的缘故；（3）玻璃材料具有极低的体积面积比，散热快、损耗低，所以上转换效率较高，激光阈值低；（4）输出激光波长多：这是因为稀土离子能级非常丰富及其稀土离子种类之多；（5）可调谐性：由于稀土离子能级宽和玻璃光纤的荧光谱较宽。

（6）由于光纤激光器的諧振腔内无光学鏡片，具有免调节、免维护、高稳定性的优点，这是传统激光器无法比拟的。

（7）光纤导出，使得激光器能轻易胜任各种多维任意空间加工应用，使机械系统的设计变得非常简单。

（8）胜任恶劣的工作环境，对灰尘、震荡、冲击、湿度、温度具有很高的容忍度。

（9）不需热电制冷和水冷，只需简单的风冷。

（10）高的电光效率：综合电光效率高达20%以上，大幅度节约工作时的耗电，节约运行成本。

（11）高功率,目前商用化的光纤激光器是六千瓦。

高功率的光纤激光器及其包层泵浦技术双包层光纤的出现无疑是光纤领域的一大突破，它使得高功率的光纤激光器和高功率的光放大器的制作成为现实。

自1988年E Snitzer首次描述包层泵浦光纤激光器以来，包层泵浦技术已被广泛地应用到光纤激光器和光纤放大器等领域，成为制作高功率光纤激光器首选途径。

连续波千瓦级, 高功率光纤激光器研制方案I. 引言激光二极管泵浦光纤激光器, 具有许多独特的优点: 特高的转换效率, 光转换效率> 85%, 电光功率效率介于30% -- 50% ; 极好的光束质量, 光束的衍射极限M² ≤1.05; 设计简单, 结构紧凑, 体积小, 重量轻, 稳定可靠性高; 大表面积-体积比,易于散热,能进行有效的热管理; 长寿命，少维修, 并有一个坚实可靠的共振腔.连续波千瓦级, 高功率光纤激光器. 由于, 它在工业和国防军事上的特殊需要. 目前,美国和英国, 已投入了大量人力和物力, 并列入国家重大项目, 进行攻关研究. 例如, 美国的高功率光纤激光器, 由国防部, 国家防御先进研究课题部门( DARPA[1] ) 负责管理, 制定规化, 投资了大量资金, 进行开发研究. 美国的空军, Northrop Grumman空间技术公司,波音公司,斯坦福大学,英国的SPI公司[2], 南安埔登大学光电子研究中心等单位, 都签定了攻关合同.目前,世界上,仅有美国IPG公司和英国SPI公司, 可提供最大输出功率, 分别为10千瓦和两千瓦, 高功率光纤激光器商业化产品. 一般说来, 连续波千瓦级, 高功率光纤激光器, 很敏感, 美国不可能批准该产品的出售. 特建议国家有关部门, 组织人力和物力, 尽快开展自主创新研究.II. 目标: 连续波1千瓦(1kW)高功率光纤激光器样机的研制图1.表示: 激光二极管堆，单根光纤, 双端泵浦，千瓦级光纤激光器的结构.∙Yb-doped large-core fiber -- 表示掺镱的大模面积, 双包层单模或少模石英光纤. 也可表示, 掺镱的大模面积, 双包层光子晶体石英光纤.∙975 nm Pump source -- 表示975纳米波长, 多模光纤耦合, 激光二极管堆高功率泵浦模块. 其多模光纤纤芯直径为600µm -1000µm，激光二极管模块, 经多模光纤耦合后, 其输出功率为400W - 1kW.∙Signal feedback for external cavity - 此处为光纤激光器的后反射腔镜.该反射镜,在1080nm激光波长处,涂有高反射介质膜层.∙Angled facet -- 该处为掺镱大模面积, 双包层单模石英光纤的后输出端面, 该端面为斜面,并涂有激光和泵浦波长的高增透介质膜层. 它也是泵浦光的输入面.∙Polished facet with high damage threshold -- 该处为掺镱的大模面积, 双包层,单模石英光纤的前端面, 其端表面与双包层光纤光轴成直角, 并涂有975纳米泵浦波长的高增透介质膜层. 该端面, 是泵浦光的输入面, 也是光纤激光器的输出端，它由双包层光纤解理或抛光制成, 其反射率为4% .图1.显示的激光二极管堆, 单根光纤, 双端泵浦, 千瓦级光纤激光器的研制方案. 在方案中, 采用掺镱双包层石英光纤, 作为高功率光纤激光器的增益介质, 其主要原因是稀土杂质镱, 能以较高浓度掺入石英光纤, 并有较小的量子淬灭效应, 这意味著, 掺镱光纤激光器, 可获得较高的光转换效率, 较小的热产生, 易于热管理, 并可实现高功率激光输出.III.光纤激光器重要组成及分系统:1. 激光增益介质:采用掺镱的大模面积, 双包层, 单模或少模石英光纤作为高功率光纤激光器的增益介质( 亦可采用掺镱的大模面积双包层光子晶体石英光纤作为激光介质), 对掺镱双包层单模石英光纤有如下要求:a. 掺镱的浓度要高, 一般要高于4500 ppm ( wt ).b. 在维持单模或少模时, 双包层石英光纤的纤芯直径要大, 其直径大于30µm.c. 为有效地利用激光二极管堆的泵浦功率, 双包层石英光纤的内包层直径, 也要尽可能大. 一般说来, 内包层直径, 在400µm - 600µm 之间. 但是, 内包层直径太大, 也会降低泵浦光的吸收系数.d. 一般说来, 掺镱双包层石英光纤, 纤芯的数值孔径(NA)为0.06, 低数值孔径是为了保证, 在维持单模或少模时, 获得大模面积或大的纤芯直径. 掺镱双包层石英光纤包层的数值孔径(NA)为0.48, 掺镱双包层光子晶体石英光纤, 包层的数值孔径为0.55 – 0.62. 较大的包层数值孔径,有利于激光二极管堆, 高功率光纤耦合泵浦模块, 将泵浦光高效率地, 注入掺镱大模面积, 双包层石英光纤.2. 激光器共振腔:现将, 千瓦级光纤激光器的共振腔结构简述如下:a. 激光器的后共振腔镜: 采用高光学质量石英片作介质, 在石英片的一个表面, 涂镀激光中心波长为1080纳米, 带宽从1070 nm – 1100 nm ( 带宽30纳米) 的高反射膜层. 这里, 采用宽带增益放大, 即可获得高功率激光输出, 同时, 也可避免高功率下, 激光介质膜层的损坏.b. 激光器的前共振腔镜:也是光纤激光器的耦合输出镜, 它是由双包层光纤解理或抛光制成, 该腔面与双包层光纤光轴垂直, 其反射率为4% , 该表面的反射率, 由石英本身的折射率决定. 该端面, 也是激光二极管堆, 高功率泵浦模块的耦合输入面, 并要求, 在其面上涂镀975纳米泵浦波长的高增透介质膜层.3. 激光器泵浦源:千瓦级光纤激光器的泵浦源: 由10-20个激光二极管棒( Laser diode bar ), 叠加成激光二极管堆( Laser diode stack ), 并采用,特殊的微光学系统与多模光纤耦合组成,即是激光二极管堆, 多模光纤耦合高功率泵浦模块. 目前,该模块的多模光纤直径为600µm, 数值孔径(NA)为0.22, 输出功率达500 瓦. 一般说来, 激光二极管棒长为1厘米, 由19个宽条型, 激光二极管组成, 其输出功率为40瓦. 近来, 美国nlight 公司, 将单个激光二极管棒的输出功率, 已提高为80瓦, 故高功率光纤泵浦模块, 不久, 就可达1000 瓦.图2.表示: 激光二极管堆, 采用微光学系统聚焦多光束的图解.图3.表示: 采用微光学系统, 将激光二极管堆的多光束聚焦后, 耦合进入多模光纤.IV. 关键技术问题的分析和解决:1. 掺镱(Yb-doped) 大模面积(LMA), 双包层(DC), 单模石英光纤的选择:a. 要求掺镱双包层石英光纤, 具有较低的本底损耗( Low background loss ):一般说来, 在1200纳米波长处, 要求掺镱石英光纤的本底损耗小于40dB/km, 即0.4dB/10 m. 这意味著, 采用10米长度的掺镱双包层石英光纤, 作为激光增益介质,激光和泵浦光的本底吸收, 仅为1% 左右, 对千瓦级光纤激光系统, 产生的热影响不大.b. 要求掺镱双包层石英光纤, 具有较高的掺镱浓度:一般说来, 双包层石英光纤, 要求掺镱的浓度Nt ≥ 4500 ppm ( wt ).据光纤激光器的理论，每米激光放大光纤, 输出的最大功率,由下式描述：P max = (hνp) · N t · S core/ t s( 1 )从( 1 ) 式可看出, 光纤激光器中可抽取的能量, 主要取决于放大光纤中掺杂的浓度N t, 萤光寿命t s , 纤芯的截面积S core，其中hνp是泵浦光子的能量。
