Claim 0:
1. A method of synthesizing apatite powder using a laser, the method comprising:
(a) immersing a substrate in an apatite-forming precursor solution;
(b) emitting a laser beam to a region on the substrate immersed in the precursor solution; and
(c) separating and drying apatite powder generated in the precursor solution,
wherein an apatite coating film is formed on the substrate and the apatite powder is generated in the precursor solution in the step (b),
wherein apatite powder is represented by Formula 1 below:

(M1)a(M2)10-a(ZO4)6(X)2  Formula 1

wherein M1 and M2 are each independently selected from the group consisting of Ca2+, Pb2+, Sr2+, Mg2+, Fe2+, Mn2+, Cd2+, Ba2+, Co2+, Ni2+, Cu2+, Zn2+, Sn2+, Eu2+, Na+, K+, Li+, Rb+, NH4+, La3+, Ce3+, Sm3+, Eu3+, Y3+, Bi3+, Cr3+, Th4+, U4+, and U6+,
