class="relatedlink">理论</a>，一个光子使得受激原子发出一个相同的光子。 <br><br>1953年：美国<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>学家Charles Townes用微波实现了<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>器的前身：微波受激发射放大(英文首字母缩写maser)。<br><br>1957年：Townes的博士生Gordon Gould创造了“laser”这个单词，从理论上指出可以用光激发原子，产生一束相干光束，之后人们为其申请了专利，相关法律纠纷维持了近30年。<br><br>1960年：美国加州Hughes 实验室的Theodore Maiman实现了第一束激光。<br><br>1961年: 激光首次在外科手术中用于杀灭视网膜肿瘤。<br><br>1962年: 发明<a href="http://sensor.oecr.com" target="_blank" class="relatedlink">半导体</a>二极管激光器，这是今天小型商用激光器的支柱。<br><br>1969年：激光用于遥感勘测，激光被射向阿波罗11号放在月球表面的反射器，测得的地月距离误差在几米范围内。<br><br>1971年: 激光进入艺术世界，用于舞台光影效果，以及激光<a href="http://holographic.oecr.com" target="_blank" class="relatedlink">全息</a>摄像。英国籍匈牙利裔物理学家Dennis Gabor凭借对全息摄像的研究获得诺贝尔奖。<br><br>1974年: 第一个超市条形码扫描器出现。<br><br>1975年: IBM投放第一台商用机光打印机。<br><br>1978年: 飞利浦制造出第一台激光盘(LD)播放机，不过价格很高。<br><br>1982年: 第一台紧凑碟片(CD)播放机出现，第一部CD盘是美国歌手Billy Joel在1978年的专辑52nd Street。<br><br>1983年: 里根总统发表了“星球大战”的演讲，描绘了基于太空的激光武器。<br><br>1988年: 北美和欧洲间架设了第一根光纤，用光脉冲来传输数据。<br><br>1990年：激光用于制造业，包括集成<a href="http://electronic.oecr.com" target="_blank" class="relatedlink">电路</a>和汽车制造。<br><br>1991年: 第一次用激光治疗近视，海湾战争中第一次用激光制导导弹。<br><br>1996年: 东芝推出数字多用途光盘(DVD)播放器。<br><br>2008年: 法国神经外科学家使用广导纤维激光和微创手术技术治疗了脑瘤。<br><br>2010年: 美国国家核安全管理局(NNSA)表示，通过使用192束激光来束缚核聚变的反应原料、氢的同位素氘(质量数2)和氚(质量数3)，解决了核聚变的一个关键困难。</td></tr></table> <!--[diy=diycontentbottom]--><div id="diycontentbottom"
