libs 为什么 用 1064nm激光器

I could answer the question;
Normally for LIBS applications,at the laser side,the keypoint is peak power density(MW/cm2),or energy density(J/cm2);
So any pulsed lasers which could offer the necessary peak power to breakdown the sample would be ok for LIBS;
Your question...why to apply 1064,it because Nd:YAG laser with fundamental output would be the choice which have the best cost performance,because Nd:YAG pulsed laser is very very mature technology;
Of course you also could choose other harmonic generation(HG) of YAG,e.g.532,355,266,213;and nitrogen laser(337),excimer laser(157/193/248/308/351),Nd:glass laser,ultrafast lasers would also possible be good choice for LIBS,but perhaps would be more expensive,or much more expensive.
***
Of course from the other side the more important key point for LIBS is high resolution &broadband scanning free ,spectroscopy with time management at nanosecond level.
***
Hope I could help you!
