  The discovery of multiple charge-density-wave (CDW) orders in superconducting
cuprates and Kagome CsV3Sb5 has offered a unique milieu for studying the
interplay of CDW and superconductivity and altered our perspective on their
nature. Here, we report a high-pressure study of quasi-one-dimensional CDW
material CuTe through ultralow-temperature (400 mK) electrical transport and
temperature-dependent Raman spectroscopy measurements and first-principles
calculations. We provide solid evidence that the pristine CDW order (CDW1)
transforms into a distinct CDW order (CDW2) at ~6.5 GPa. Calculations show that
the driving force of CDW1 is due to the nesting effect and that of CDW2
probably arises from the electronic correlated interaction. Strikingly,
pressure-induced superconductivity is observed with a dome-like phase diagram
and its transition displays an extraordinary broadening along with the
crossover from CDW1 to CDW2. These results demonstrate that pressurized CuTe
provides a promising playground for understanding the intricated interplay of
multiple CDWs and superconductivity.
