Abstract
Organic semiconductors lasers (OSLs) do not naturally operate in the Continuous-Wave (CW) regime due to the accumulation of long-lived triplet states. Recently, however, triplet engineering has allowed quasi-CW lasing, notably in BSBCz and its derivatives. An analysis of CW lasing conditions in organic semiconductors that includes the effects of Triplet Absorption, Singlet-Triplet-Annihilation, Triplet-Triplet Annihilation or Reverse Intersystem Crossing is presented. In addition of photophysical parameters, we show the crucial role played by the resonator Q factor in the lasing regime. This work provides a roadmap towards true-CW lasing based on a global approach that encompasses photophysics and optical design.
