本文研究了p偏振、s偏振和圆偏振激光脉冲辐照3 μm厚的Ta箔靶靶时，靶面上的质子发射。在p偏振激光脉冲的照射下，在靶法向观测到能量高达880keV的质子，产生了最高的质子发射效率。相比之下，s偏振和圆偏振激光脉冲的最大能量分别为610和680keV。p极化和s极化情况下最大能量的差异与电子能谱估计的鞘层场之间的差异有关。
A study of proton emission from a 3‐μm-thick Ta foil target irradiated by p-, s-, and circularly polarized laser pulses with respect to the target plane has been carried out. Protons with energies up to 880keV were observed in the target normal direction under the irradiation by the p-polarized laser pulse, which yielded the highest efficiency for proton emission. In contrast, s- and circularly polarized laser pulses gave the maximum energies of 610 and 680keV, respectively. The difference in the maximum energy between the p- and s-polarized cases was associated with the difference between the sheath fields estimated from electron spectra.
