Abstract
The influence of sample thickness and carrier surface recombination on the characteristics of resonatorless dissipative optical bistability (RDOB) is investigated. The RDOB under consideration is caused by the excitation density nonlinearities of band‐edge absorption of laser radiation in semiconductors. The diversity of multivalued spatial carrier distributions in the sample of thickness d with arbitrary velocity of surface recombination S are considered. It is established that strong recombination can considerably affect the structure and properties of possible carrier distributions and hysteresis of the transmission.
