还能多复杂?
<P> 看看这个附图,你的激光器不会比它更复杂多少吧?</P><img src="data/attachment/forum/dvbbs/2004-4/200442892039743.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(\'data/attachment/forum/dvbbs/2004-4/200442892039743.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><P>I have never used this laser. Is it a pulsed laser or CW? Pulsed laser is usually very sample. 2 points are important for pulsed system:</P><P>1). Timing: matching the pulse on all the dyd cells;</P><P>2). alignment: optically overlap the beam.</P><P>CW laser are usually more difficult for beginners. For pulsed laser, what to say? </P><P>"It is hard to make it not lasing"</P>
