This work provides an overview of the recent advances in the field of two-photon absorbing chromophores active in the short-wavelength infrared (SWIR) spectral range. Herein the common strategies and main structure-properties relationships that lead to a near-infrared (NIR) electronic absorption of chromophores are described. A complete review of the molecules that feature two-photon absorption (2PA) beyond 1100 nm is presented for the purpose of further use in optical power limiting applications in the SWIR band. Recent progresses in the development of optical power limiting in this particular spectral region are reported with emphasis on the use of two-photon induced excited state absorption (ESA) process as optical power limiting enhancer.
