Simulations using a two-dimensional electromagnetic and relativistic particle code show that high-frequency Langmuir waves can be generated by a plasma maser mechanism from low-frequency whistler waves excited by electron temperature anisotropy. It is confirmed that the plasma maser mechanism does not require an electron beam component for the generation of high-frequency Langmuir waves. We are forced to reconsider the emission mechanism of Langmuir waves observed in space plasmas.
