摘要： The process of ionizing normal saline induced by femtosecond laser is studied from the perspective of gas production rate and composition. When the repetition rate is less than 1000 Hz, each laser pulse independently generates ionization gas. At the same time, we discovered the inhibitory effect of meglumini diatrizoici on the ionization process and explained the reasons for this inhibition. Finally, the gas composition proved that the primary gas production mechanism of the femtosecond laser is the decomposition of water molecular, and the composition of the solution after the reaction proved the decomposition effect of the laser on meglumine.
