Query: Observation of two types of charge density wave orders in
  superconducting La$_{2-x}$Sr$_x$CuO$_4$   The discovery of charge- and spin-density-wave (CDW/SDW) orders in
superconducting cuprates has altered our perspective on the nature of
high-temperature superconductivity (SC). However, it has proven difficult to
fully elucidate the relationship between the density wave orders and SC. Here
using resonant soft X-ray scattering we study the archetypal cuprate,
La$_{2-x}$Sr$_x$CuO$_4$ (LSCO) over a broad doping range. We reveal the
existence of two types of CDW orders in LSCO, namely CDW stripe order and CDW
short-range order (SRO). While the CDW-SRO is suppressed by SC, it is partially
transformed into the CDW stripe order with developing SDW stripe order near the
superconducting $T_{\rm c}$. These findings indicate that the stripe orders and
SC are inhomogeneously distributed in the superconducting CuO$_2$ planes of
LSCO. This further suggests a new perspective on the putative pair-density-wave
order that coexists with SC, SDW, and CDW orders.
