peak power<br /> Low heat waste,air cooling<br /> <br /> WEDGE emits pulses of 1.5 mJ energy at 1064 nm, duration shorter than 1.5 ns and peak powers exceeding 1 MW.<br /> Based on a proprietary electrooptic Q-switching technology,this monolithic laser source features a very high peak power with excellent wall plug efficiency.<br /> <br /> The sealed miniaturized laser head is insensitive to vibrations and harsh environments. High output peak power with relatively low Q-switch energy allows efficient nonlinear harmonic or parametric generation as well as interaction with a wide range of materials.<br /> <br /> Harmonic options available:<br /> <br /> Second harmonic @ 532 nm<br /> Third harmonic @ 355 nm<br /> Two mechanical configurations available:<br /> <br /> Single Unit.<br /> Dual Unit. A Resonator Unit is linked to a Pumping Unit via a fiber optic cable and a Q-switch cable.<br /> Both the versions have built-in finned heat exchangers for air cooling.<br /> <br /> Applications<br /> Nonlinear spectroscopy<br /> 2nd and 3rd harmonic generation<br /> Visible to IR OPO pumping<br /> Material processing<br /> Surface and intra-volume glass marking</div> <div class="postmsg">如果为了达到1ns的脉宽，却使得频率不能连续调节就没有什么意义了</div> <div class="postmsg">但有的用户就是需要窄脉宽，其他的不要求。<br /> 另外还有需要激光脉宽1～30ns连续可调的，不知各位有何高见？</div> <div style="height200px;"></div> <ul class="xl xl2 cl" style="border-top: 1px #cccccc dashed;margin:5px 0 ;padding-top:5px"> <dl><b> 同一主题资料:</b></dl><dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29022" title="ViewFull.pdf">ViewFull.pdf</a> <font color="#AAAAAA">(702.3 KB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29023" title="ViewFull3.pdf">ViewFull3.pdf</a> <font color="#AAAAAA">(1.42 MB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29024" title="ViewFull12.pdf">ViewFull12.pdf</a> <font color="#AAAAAA">(206.89 KB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29025" title="ViewFull.pdf">ViewFull.pdf</a> <font color="#AAAAAA">(702.3 KB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29026" title="ViewFull3.pdf">ViewFull3.pdf</a> <font color="#AAAAAA">(1.42 MB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29027" title="ViewFull.pdf">ViewFull.pdf</a> <font color="#AAAAAA">(702.3 KB)</font> </dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=29057" title="调Q激光自触发斩波产生纳秒脉宽单脉冲激光.pdf">调Q激光自触发斩波产生纳秒脉宽单脉冲激光.pdf</a> <font color="#AAAAAA">(392.53 KB)</font> </dl> </div> </div> </div> </div></div> </div> <!--autocomment filter by maxnum--> <div class="ft_wp"> <div id="ft" class=" cl"> <div id="flk" > <p> <a href="http://wpa.qq.com/msgrd?V=3&Uin=20600600&Site=光电工程师社区&Menu=yes&from=discuz" target="_blank" title="QQ"><img src="static/image/common/site_qq.jpg" alt="QQ" /></a><span class="pipe">|</span><a href="http://m.oecr.com" >手机版</a><span class="pipe">|</span><a href="http://so.oecr.com" title="站内搜索" target="_blank" >搜索</a><span class="pipe">|</span><a href="http://www.focaloptics.com" title="主办单位：武汉焦点光学技术有限公司" target="_blank" >焦点光学</a><span class="pipe">|</span><a href="http://www.oecr.com" target="_blank">光电工程师社区</a> ( <a href="http://beian.miit.gov.cn/" target="_blank">鄂ICP备17021725号-1</a> <a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821" target="_blank">鄂网安备42011102000821号</a> ) <span id="tcss"></span><script type="text/javascript" src="http://tcss.qq.com/ping.js?v=1eOg" charset="utf-8"></script><script type="text/javascript" reload="1">pgvMain({"discuzParams":{"r2":"1028778","ui":0,"rt":"plugin","pn":1,"qq":"000"},"extraParams":""});</script></p> <p class="xs0"> <span id="debuginfo"> Copyright 2015 光电工程师社区 版权所有 All Rights Reserved. </span> </p> </div> <div id="ftl" > <p>申明：本站为非盈利性公益个人网站，已关闭注册功能，本站所有内容均为网络收集整理，不代表本站立场。如您对某些内容有质疑或不快，请及时联系我们处理！ </p> </div> <div id="frt" > <div class="wp"> <p class="dd01"> © 2001-2022 <a href="http://www.oecr.com" target="_blank">光电工程师社区</a> 网站备案号：<a href="https://beian.miit.gov.cn/">鄂ICP备17021725号</a> 网站公安备案号：<a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821">鄂42011102000821号</a> Powered by <a href="http://www.discuz.net" target="_blank">Discuz!</a> <em>X3.2</em> </p><p class="dd02">GMT+8, 2025-12-22 14:35 </p> </div> </div></div> </div> </div> <!--bottombg结束--> <script src="home.php?mod=misc&ac=sendmail&rand=1766385341" type="text/javascript"></script> <!--<div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> --> <div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> <script type="text/javascript">_attachEvent(window, 'scroll', function () { showTopLink(); });checkBlind();</script> <div id="discuz_tips" style="display:none;"></div> <script type="text/javascript"> var tipsinfo = '1028778|X3.2|0.6||0||0|7|1766385341|2be551a3aacd0d9e86dcfa6b2c8b1ca5|2'; </script> <script src="http://discuz.gtimg.cn/cloud/scripts/discuz_tips.js?v=1" type="text/javascript" charset="UTF-8"></script></body></html>
