哦，原来是这样，真遗憾，
<P>You guys do not understand the situation. Prof. Xu 's project is the way to amplified fs laser, but I do not know the exactly the project of Physics Institute. I read one paper from Wei's group which is ugly. Any way, the commercial fs laser is easy to get under 20fs. One I am doing by myself is somehow too short,which is about 16fs. And what I am using just commercial TS and mirrors.</P><P>The fs is not aims now, but as laser.</P>
好象中山大学能做N个飞秒
原来是这样，我明白了，飞秒不是目的，而是激光，是吗？，徐先生的重点在于放大飞秒激光，谢谢

<P>To my knowledge, the fs lasers oscillation of Prof. Wei have been sold to Japan. This is pretty
<P>cool I think. You should know you can not judge only by the papers. Sometimes papers is garbage.</P>
<P>i know,thank you very much</P>
<P>世界上第一个产生4～5飞秒的人是中科院西安光机所的程昭在奥地利实现的，现在是西安光机所的百人计划之一，另外中科院北京物理所的魏志义老师也能做了！</P>
I have been heard recently, Prof. Wei had sold the fs oscillator and amplifier to Japan.

<P>They are much cheaper than Spectro Physics and Coherent. </P>
<P>物理所的是便宜，不过稳定性比相干和光谱的要差一些了，不过在国内来说他们做的算不错了</P>

<P>阁下用过魏老师做的激光器吗？</P>
不清楚呀！
