激光加工工程;前 言;激光导引星，让地面的望远镜能更清晰地做天文观测。这项技术被军方用来侦测卫星，比如说，看清卫星表面的标记来判定国别。天文学家在夏威夷的Keck天文台，利用激光导引星，拍摄了第一张银河系中心的清晰照片，包括黑洞附近区域。;2005 年激光领域最大的突破是硅激光，英特尔在年初首先报道了连续波全硅拉曼激光器，作者是 Haisheng Rong。荣海生在南开大学物理系获得学士与硕士学位，德国海德堡大学激光光谱博士学位。1996年加入麻省理工与加州理工学院合作的项目“激光干涉仪” 。2000年到硅谷在New Focus做光通讯研究。2002年加入英特尔的硅光研究团队。 苏格兰南部， 2005 1月9日，天空中有奇怪的光和奇形怪状的物体。被证实是一场激光秀产生的，那里在举行一场婚礼。 两颗处在不同轨道的卫星成功地使用激光实现了信息交换。这项技术未来可能会应用在太空船间的超高速通讯上。因为激光比无线电发送器频率高，因此可以在相同的时间内传递更多的信息。;激光测量;激光打标 ;;激光枪 ;第1章 激光在军事上的应用 ;;;;;;;;;;;Lasers are being applied more and more widely in the manufacturing environment. Lasers provide a very particular way of applying thermal energy to material, leading to a wide variety of welding, cutting, and surface treatment processes。 Drill the Hoes Weld Cut Out Material for Sewing Clothes Weld Razor Blades Weld, Clad, Cut Parts For Cars Drill the Holes In Jet Engine Turbine Blades Engrave Tombstones;;;;;;;;;;;第3章 激光加工系统 ;;HAAS-LASER 4 KW Nd:YA;Laser Micromachining Prototyping Laboratory ;;LASERS ARE VERY GOOD FOR Putting lots of energy (heat) in a small spaceControlling that energyAffecting selectively one material versus another – even when the two are in intimate contactHigh production rate;;INDUSTRIAL LASER COMPARISON＠ CO2 lasers （10.6 micron characteristic wavelength，pulsed or continuous wave output）continuous wave power output up to 45 kW pulse system average power up to 6 kW reflective optics, especially at higher power ＠ Nd:YAG lasers （1.06 micron characteristic wavelength ，pulsed or continuous wave output ） power output of continuous wave up to 5 kW pulse system average power up to 2 kW fiber optic beam delivery ;BEAM DELIVERY USING MIRRORS, LENSES （CO2 and Nd:YAG ）;;The prototype tooling industry is about 300 Billion dollar a year industry. Prototype parts are often used by designers to test alternative designs. Prototype parts can range from conceptual to functional. Barkan and Iansiti developed a detail study of the levels a prototyping stages which
