to 1: We have modified according to his suggestion.
to 2: This idea is proposed by us and hence there is no reference. As for "possibility", it is warranted by basic physics principle. Lever principle should not be doubted.
to 3: We use larger characters in Fig.2.
to 4: We have listed related references which are on technique details of our simulation to be conducted. Because at present we have not rent computer source, the simulation have yet not conducted. Therefore, a concrete citation on simulation result is unavailable now.
to 5: It is really difficult to explain these parameters from Eq.(6) because their introductions are for convinience of displaying mathematics formula, for example, making a long formula to be short. We of course wish our manuscript to be presented in, as the referee said, a "serious way of writting the report". But this time we really cannot make more meanful improvement on this item. After all, they have been published elsewhere.
to 6: The purpose of this draft is to outline a technique route, whose feasibility is warranted by presented theory agreeing with basic physics principle. As for proof-of-principle evidence or references, we wish interested researchers to conduct relevant experiments. Our duty in this work is to theoretically confirm its feasibility in "efficiently generate radiations at desired wavelength and time-duration".Now that the referee has perceieved that "the core idea ... is ... electron bunch will oscillate in a controlled manner", we think that the statement "efficiently generate radiations ..." is appropriate (because it does not exaggerate anything).
