This paper reports the initial results of droplet vaporization behavior suspended by optical tweezers. The main concept of this study is to observe noncontact droplet in order to eliminate the fiber effects and the vaporization of water droplets were successfully observed. The maximum diameter of suspended droplet is around 16 μm and the vaporization rate constant are the order of 10^<-5>mm^2/s. The effects on the vaporization of surface tension and convection around the droplet are discussed. As a result, the vapor concentration of ambient dominantly affects vaporization behavior and the improvement of ambient condition control was suggested.
