Numerical simulations reveal that laser action in random media occurs when gain balances the decay rate of the longest-lived quasistate. The lasing threshold dependence on scatterer number (N) follows a 1/sqrt(N) relationship, linked to decay rate fluctuations.

Area of Science:

  • * Physics, Optics, and Photonics
  • * Condensed Matter Physics
  • * Quantum Optics

Background:

  • * Random media exhibit unique light propagation and interaction phenomena.
  • * Understanding laser action in disordered systems is crucial for novel photonic devices.
  • * Quasistates in finite random systems are characterized by decay rates due to light leakage.

Purpose of the Study:

  • * To numerically investigate laser action in a planar random medium composed of resonant scatterers.
  • * To determine the dependence of the lasing threshold on system size (number of scatterers).
  • * To explore the role of quasistate decay rate fluctuations in laser behavior.

Main Methods:

  • * Numerical simulation of a planar system of resonant scatterers.

Related Experiment Videos

  • * Analysis of eigenmodes (quasistates) and their decay rates.
  • * Modeling of gain compensation for quasistate decay.

    • Main Results:

    • * Lasing initiates when optical gain overcomes the decay rate of the longest-lived quasistate.
    • * The lasing threshold intensity scales with the inverse square root of the number of scatterers (N).
    • * This scaling is strongly correlated with fluctuations in quasistate decay rates.

    Conclusions:

    • * The 1/sqrt(N) dependence of the lasing threshold in random media is explained by quasistate decay rate fluctuations.
    • * The findings align with recent experimental observations in disordered lasers.
    • * Further investigation into the nature of these fluctuations is warranted for controlling laser properties.
