Corrigendum Text: On page 2 of this letter, there is a misprint in the unit. The unit of the geometrical dimension of the spherical hohlraums on this page should always be “mm” rather than “mm”, i.e. in the second paragraph, “…with 800 J per beam at 0.35 mm…” should be “…with 800 J per beam at 0.35 μm…”, “The slit of 400 mm width is parallel…” should be “The slit of 400 μm width is parallel…”, “The laser focal diameter is about 500 mm…” should be “The laser focal diameter is about 500 μm…”; in the third paragraph, “…we take 850 μm as the radius…” should be “…we take 850 mm as the radius…”, “The LEH radius RL is 400 mm…” should be “The LEH radius RL is 400 μm…”, “…the radius of the cylindrical LEH outer ring is taken as 1.5 RL = 600 mm” should be “…the radius of the cylindrical LEH outer ring is taken as 1.5 RL = 600 μm”. This mistake does not affect any of the main results of the original letter.

There is a misprint in the text of Figs. 3 and 4. The text on the bottom part of Figs. 3 and 4 should be “100 fs pulse Photoexcitation” and “1 fs pulse Photoexcitation” respectively. This error does not affect any conclusions in this work, and it has been corrected in the printed version of the journal.
