  We present a study of optical quantum states generated by subtraction of
photons from the thermal state. Some aspects of their photon number and
quadrature distributions are discussed and checked experimentally. We
demonstrate an original method of up to ten photon subtracted state preparation
with use of just one single-photon detector. All the states where measured with
use of balanced homodyne technique, and the corresponding density matrices
where reconstructed. The fidelity between desired and reconstructed states
exceeds 99%
