Thermal effect is one of the most important factors to limit the output characteristics of high energy lasers, and the liquid laser has special predominance on heat managements. An experiment on inorganic liquid laser pumped with laser diode at flowing state is carried out, and high repeating frequency laser pulse output is achieved in a long time. The laser spectrum,the laser pulse shape, and the single laser pulse energy are measured. The laser center wavelength is 1052.7 nm, the laser pulse time width is 170 μs, and the maximum single laser pulse energy is about 5 mJ. The liquid laser can continue running more than 10 min under pumping frequency of 400 Hz. The pulse energy will decrease with the pump frequency increasing. The experimental results show that the inorganic liquid laser system pumped by laser diode can avoid heat deposition effectively at flowing state, and achieve high repeating frequency laser pulse output in a long time, which has the potential to develop into newstyle high power and high beam quality laser system, and is worth carring out deeper experimental research.
