Abstract

Using an improved borosilicate glass with small third-order optical nonlinearities, i.e., nonlinear refractive index (NLRI) and nonlinear absorption coefficient (NLAC), as the matrix and comparative glass, two types of Ho³⁺-doped glass are prepared with a solid-phase smelting process at a relatively low temperature, and their third-order optical nonlinearities are measured by the closed-aperture Z-scan technique using nanosecond laser pulses at 532nm wavelength. It is found that the matrix glass possesses a positive third-order NLRI and a positive third-order NLAC, and both the third-order NLRI and NLAC of Ho³⁺-doped glasses are one order larger than those of the matrix glass, respectively. Also, an open-aperture Z-scan experiment and an optical limiting experiment further demonstrate that the Ho³⁺-doped glasses have a high third-order NLAC. All the experimental results show that this Ho³⁺-doped glasses have good protection performance for the 532nm-laser.
