The photoconductive, orientational, and photorefractive properties of monolithic glasses based on new nonlinear optical chromophores containing a 2‐dicyanomethylene‐3‐cyano‐2,5‐dihydrofuran (DCDHF) acceptor group are presented. Large net gain coefficients are observed in both red and infrared wavelength regions. The physical and optical properties of glasses based on various DCDHF‐containing derivatives are compared and analyzed, and the factors limiting steady‐state and dynamical photorefractive performance are discussed.
