  "abstract": "Discrete time crystals (DTC) can respond at an integer multiple of the drive period. Internal order-parameter measurements have advanced studies of this novel non-equilibrium phase of matter; however, turning this order into highly coherent, externally accessible radiation remains challenging: pump-driven nonlinear processes must supply sufficient gain to compensate dissipation while preserving subharmonic stability. Here we realize a room-temperature magnonic time crystal (MTC) with radiation of lasing coherence using a pump-induced magnon mode in yttrium iron garnet. A microwave beat drive produces robust period doubling over a finite parameter range, with spectral signatures of higher-order MTC at stronger driving. The emitted field exhibits linewidth narrowing to 260.0 Hz and a first-order correlation decay time of $995 μs$. Our model links this response to three-magnon confluence, yields a stability region consistent with experiment and predicts a possible transition to chaos. We further map the complex temporal dynamics into frequency-resolved nonlinear features for reservoir computing. These results bridge time-crystalline order and nonlinear information processing through intrinsic magnon-magnon interactions and lasing coherence.",
