摘要: A specific-wavelength infrared (IR) light (λ=3140 nm) was irradiated into a solid D2 ice prepared in a cylinder target cell. The temperature in the solid D2 ice oscillated periodically with a high amplitude when irradiated by the IR light. The temperature oscillation has been well explained based on the two-dimensional heat transfer theory plus the IR-irradiation effect. The transmission optical imaging reveals that such a temperature oscillation is favorable to recrystallize the solid D2 ice from multicrystal to quasi single crystal. This suggests an efficient method to layer the solid hydrogen-isotope ice for the inertial-confinement-fusion (ICF) experiments.
