class="postmsg">老化光斑不稳定也只是少数，是个成品率的问题。目前我们做的微片200mW寿命可以做到5000hrs以上。</div> <div class="postmsg">尺寸我们有做的更小的，最小尺寸到4mm*5.3mm*14mm，输出功率达100mW以上</div> <div class="postmsg">上面的尺寸是封装后的激光器尺寸</div> <div class="postmsg">光斑质量及其稳定性是很重要的，比如激光投影显示，对光斑质量和稳定性要求是很好的；如果只是做Pointer，有点大材小用了。</div> <div class="postmsg">whh8642 及所在公司在这方面是很有创新的.顶一个.<br /> 主要是用在激光显示方面吧,还有手机投影,有没有批量化生产呢?有没有偏振方面的要求呢?晶体尺寸(没封装)会有多大?</div> <div class="postmsg">该微片激光器腔长有多长呢?<br /> 多模很可能是因为泵浦光模体积与基频光振荡模体积不匹配,即模式匹配不好.<br /> 光斑不稳也可能是因为采用深化光胶工艺后晶体应力太大<br /> 能不能给个该晶体的照片???或报个大至的尺寸???</div> <div class="postmsg">光斑不稳也可能是因为采用深化光胶工艺后晶体应力太大，这个我们也一直怀疑，也进行了很多实验，但是也找不到直接证据。</div> <div class="postmsg">微片尺寸不大，三维：1mm*1mm*3~10mm,随着输出功率的不同以及其它特性参数的变化，腔结构会有变化。</div> <div class="postmsg">目前来说，我们的这种产品在国际上应都是领先的。其主要特点是高效率(电光效率超过15％,至少30度温宽)，低噪声、偏振输出。</div> <div class="postmsg">看来号称全球领先的福晶也不是你们对手哈哈</div> <div class="postmsg">福晶主要是晶体的，这个强大家应该没有什么疑问，但是光胶晶体技术我们确实做的比较靠前，福晶的光胶晶体现在买的很好，说到底还是因为其品牌的缘故。</div> <div class="postmsg"><i class="pstatus"> 本帖最后由 xbdxwm 于 2009-5-22 12:44 编辑 </i><br /> <br /> 就这点技术成天在这吹，不就加个了东西或改改尺寸结构的吗，整了几年的这个，感觉没意思啦，我有技术谁要，开卖了，开始竞价。。。</div> <div class="postmsg">王兄，今天让你看了，一个星期之后就大批量出产了啊</div> <div class="postmsg">我见过用500mW的808用胶合晶体出150mW的绿光的产品</div> <div

但就算什么都是旧的或大家熟知的技术,能产品化,市场化也是不容易的.<br /> 深化光胶后的微片激光器光斑质量不好,其实就是最大的问题,效率及温宽其实不是大不了的问题</div> <div class="postmsg">xbdxwm 是不是荷尔蒙分泌太多了，这么激动。如果你真懂的话，说话还是要严谨点。</div> <div
