Low‐threshold two‐photon‐pumped (TPP) perovskite microcavity lasers are achieved in crystal perovskite 1D or 2D microstructures fabricated through a liquid‐phase self‐assembly method assisted by two distinct surfactant soft templates. The lasing actions from the perovskite materials exhibit a shape‐dependent microcavity effect, which is subsequently utilized for the modulation of the lasing modes and for the achievement of two‐photon‐pumped single‐mode perovskite microlasers.
