[贴图]今天暴力分解了我的532nm的绿光
<P>功率是50mw,是模组，今天被我拆开了，如图：</P>模组分一块电源板和激光发射模组，电源接220V市电，输入1.85V给模组。<br><br><img src="attachments/dvbbs/2005-9/20059171748694230.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/20059171748694230.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/20059171757332181.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/20059171757332181.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><br>拆开模组，里面是纯铜组件，下方是808nm的LD底座，LD就焊接在里面，发现非常微弱的红光，千万别以为功率很小，手指放上去，一秒钟烧出一个白点。。。套上镜头后（Nd:YVO4+KTP晶体）立刻发出耀眼的绿光。。。<br><br><img src="attachments/dvbbs/2005-9/200591717481536107.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/200591717481536107.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><br>上方是变频晶体，这个部分很难拆（不知道用的是什么固体胶水，粘得非常死），我用老虎钳和钢锯配合终于给撕开，如图3<br><br>晶体非常小，大概只有一平方毫米，超频的话不知道会不会炸裂....<br><img src="attachments/dvbbs/2005-9/200591717482194330.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/200591717482194330.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br>808nm的功率不知道是多少，放上一个黑色手电拉绳能迅速冒烟。<br><br><img src="attachments/dvbbs/2005-9/200591717483054501.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/200591717483054501.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200591717483861948.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/200591717483861948.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><img src="attachments/dvbbs/2005-9/200591717554040085.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-9/200591717554040085.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><br><br>修好几乎没有可能性了，发烧果然烧钱，400多块就这样没了[此贴子已经被作者于2005-9-23 13:58:27编辑过]

<P><br><br>笔式的功率比较小，而且从LD到透镜有一段距离，所以将东西堵在出光口没什么问题，不过时间最好不要太长了，有短寿的可能。我这个老化的原因主要是我将透镜都取下了（透镜到LD的距离有5-8厘米左右），将物体直接放到LD上面烧，几乎只有3-5毫米的距离，所以LD很快就因为过热老化了。。<br><br>还有10mw左右的绿光输出，我还是留着自己研究好了，呵呵：）主要是想把电路搞出来，然后再购一套改成便携的。</P>

<P>慰问一下。不知道这个808功率是多大的？是否测量了通过这管子的实际电流？这种封装应该是C-type，可以找一个换上。</P>
<P>我以前的一个5mW被调成了40mW，非常好，但由于管角旋转松动，把那个细线（只有一根、不是三根）扯断了！</P>
[此贴子已经被作者于2005-9-19 13:20:19编辑过]
808nm的管子估计是200mw左右的，经过晶体转换后出来的绿光45mw左右，KTP+Nd:YVO4晶体的转换效率可能是20%-25%左右，如果效率没这么高的话，那么808nm的管子很有可能是500mw的功率。<br><br>手头上没有万用表啊，这几天有空了去买一块...<br>
