Halide perovskites are a family of materials with a high potential for realization of microlasers, due to their high luminescence quantum yield and broad spectral tunability. We demonstrate a single-step process for lasing microdisk fabrication from a thin film of methylammonium lead iodide (MAPbI(3)) perovskite through its patterning with tightly focused femtosecond (fs) laser pulses. By using kHz-scale pulse bursts destructive overheating of the material was suppressed. Perovskite microdisks fabricated under such optimized conditions showed stable lasing upon pumping with fs-laser both at lower (50 kHz) and higher (80 MHz) repetition rates and operation temperatures of 300 K and 6 K, respectively.
