Abstract
China loess attracts attention in East Asia. In the previous research of our group, an elemental detection method with LIBS has been developed. In this work, we tried to develop the element detection method of China loess with a LD pumped passively Q-switched Nd:YAG laser. We developed the system which can duplicate appearance of China loess in the air. The breakdown thereshold of China loess blown by the air was estimated. And the required sensitivity in the system was also estimated.
