In previous studies, we have shown the appreciable reduction of pulse laser ablation threshold by laser beam reflection at the transparent material interface with air. In this study, we have tested a similar situation but using transparent energetic and non-energetic liquids in air. Whole ablation and subsequent atomization processes were observed by pulse laser shadowgraphy. Minimum laser fluence for laser ablation at water-air interface is found to be around 12-16 Jcm-2. Several kinds of liquid samples tested in the present study include water, ethanol, engine oil and kerosene. It is found that liquid atomization process is quite similar for several liquid samples, and all the energetic liquids tested can be ignited by a heated NiCr wire above the liquid surface.
