Single-step direct laser writing of halide perovskite microlasers

Abstract: 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 (MAPbI3) 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 s… Show more

“…The resonators used for lasing can be divided into three groups: random resonators, supporting random lasing (RL); [ 2–6 ] optical resonators based on the refractive index contrast between the synthesized perovskite material and air, such as micro‐ and nanocubes, [ 7–9 ] rods, [ 10,11 ] wires, [ 12–17 ] platelets, [ 18–20 ] micropyramids, [ 21 ] and microspheres; [ 22–24 ] and external resonators based on distributed Bragg reflectors, [ 25–28 ] capillary‐like microcavities, [ 29 ] photonic crystals, [ 30,31 ] gratings for distributed feedback lasers, [ 32–38 ] and nanolithographically fabricated microdisks. [ 39–41 ] The laser generation manifests itself in different ways. In most of the works, the main conclusion about the lasing nature of the emission is made based on the narrow line width and threshold behavior [ 2–5,7–16,18,19,21,22,25–27,30,32–43 ] of the emission.…”
