href="http://forum.oecr.com/forum.php?mod=redirect&goto=findpost&pid=743439&ptid=128861" target="_blank"><font color="Olive">sinostudio</font> 的帖子</a></strong><br /> <br /> 楼主在这篇文章是说固体激光的“三大”关键技术：opo，DPL，小型固体激光器。<br /> 第一、楼主的依据是96年的一篇译文，但是到了04年后DPL的泡沫也就休了！<br /> 第二、wangyaoting ，Nd:YAG ，dabaorabbit 同样认为DPL优于灯泵，这种人不少！我告诉您们，看问题要站得高一点，从全局看。你们中间有人问谁告诉我DPL不如灯泵，ILS、LFW告诉我的，灯泵、光纤、DPL三种固体激光器，在工业加工领域，灯泵的销售额占50%以上，平均单价6.5万美元，光纤3.1，DPL2.2。这个数据可以说明问题了吧！<br /> 第三、灯泵主要用在高功率高光束质量的切割中，用在微电子应用中，光纤主要用在微细打标中，弟子器件、消费类电子、IT行业等。DPL给了中国的科研界的人们一个大大的气球，可是今日还没有醒，这就是我经常笑话这些教授、专家的话题。<br /> 第四、DPL由于他的结构，始终解决不了它的光束质量和均匀性，注定了它是低端东西。<br /> 第五、从这个争论来看，水平太低了，没有想到连这样简单的事实，还有人去维护（DPL），只要您们去看一看LFW，ILS就明白的事。<br /> 第六、“三大”技术，就应该从固体激光的最主要的应用来考虑，首先是军事应用和加工。目前军事应用还没有DPL，DPL的效率加上温控的功耗，优点就没有了，你们几个说DPL效率高的，以后看问题，最好全面一点。军事应用，开发DPL也有十几年了，直径没有上型号，这就是我们必须回头好好考虑的了，为什么？您们喊口号是没有用的。工业加工50%是切割，70%是金属加工，就这个70%中鲜有DPL，这样的事实，你们可以接受了了吧？<br /> 从这在来考虑固体激光三大关键技术，楼主转的三种技术，哪一样都谈不上关键，只能说是一棵大树上的枝叶而已！<br /> 您们想想是不是需要在回回炉，从新学学固体激光？<br /> <br /> </div> <div class="postmsg">用相同的晶体，相同的腔，相同的结构，只是把灯换成LD，其他都不变。然后看看会怎么样。既然LD可以做显示器的背光源，也可以当成一种灯来看。把LD也当成一种灯来看，不考虑它的光斑、发散角什么的，用足够数量的LD让泵浦光在晶体中形成均与分布。然后，我们再来对比。然后，我们可能发现，我们之前谈论的可能不是固体和非固体的区别，而只是结构和形式的区别。</div> <div class="postmsg">允许有争论，有争论才说明大家用了心的！有自己的见解！中国的激光事业才有发展的可能！</div> <div class="postmsg"><strong>回复 <a href="http://forum.oecr.com/forum.php?mod=redirect&goto=findpost&pid=736767&ptid=128861"
