• We find that the superposition of coherent states Ψ_<scs> that generates |4m> Fock states can squeeze the electromagnetic field conjugate at both fourth order and sixth order <Ψ_<scs>|(ΔE_i)^<2N>|Ψ_<scs>><<α|(ΔE_i)^<2N>|α>_<coh> (i=1 and 2)(N=2,3). A very interesting point which the present calculation reveals is that the minimum squeezing in both the cases (i.e. N=2,3) occurs at |α|=0.67. A further interesting point is that the smallest eigenvalue of E^<2N>_i obtained by using a superposition of |4m> Fock states remains nearly the same as the minimum squeezing value: <(ΔE_i)^<2N>>_<minimumsqueezing>≃<(E_i)^<2N>>_<smallesteigenvalue> (i=1 and 2; N=2,3).
