A polydimethylsiloxane cylindrical‐hole‐template‐confined solution‐growth method is developed to fabricate densely packed CsPbCl 3− x Br x microdisk laser arrays. Furthermore, a strategy to integrate multicolored microdisk laser (MDL) arrays is demonstrated that simultaneously lase in the deep blue, blue, cyan, and green by means of gas‐phase replacement of Cl by Br from initial CsPbCl 3 MDLs in HBr vapor.
