A highly-focused laser-induced liquid microjet is expected to be applied to a needle-free injection system. For practical use of this microjet, we need to control the volume V of the microjet. Previous research had revealed that the V is described by the maximum volume Ω of the laser-induced bubble. In order to manage the Ω, we have to investigate the describing parameters of Ω. In this paper, we carry out experiments to clarify the describing parameters of Ω. We find that Ω is proportioned to the laser energy E and inversely proportional to the distance H between meniscus and laser focus point.
