Abstract

|
-photon-subtracted squeezed state 
, i.e., we construct the generating function 
and
respectively, after calculating them and comparing the result with the standard form of generating function of Legendre polynomials Pm,we find m<r|r>m=m!cosh mrPm(cosh r), 
and 
, where r is the squeezing parameter.
