  We provide a unified approach for finding the coherent states of various
deformed algebras, including quadratic, Higgs and q-deformed algebras, which
are relevant for many physical problems. For the non-compact cases, coherent
states, which are the eigenstates of the respective annihilation operators, are
constructed by finding the canonical conjugates of these operators. We give a
general procedure to map these deformed algebras to appropriate Lie algebras.
Generalized coherent states, in the Perelomov sense, follow from this
construction.
