摘要：

We demonstrate a novel use of the pump-probe thermal lens spectroscopy and Z-scan techniques for the measurement of the small absorption coefficient in a semiorganic, nonlinear optical crystal zinc (tris) thiourea sulphate. We measure the absorption spectrum and the absolute values of the absorption of the crystal in the near-infrared region (700-980 nm). A maximum absorption coefficient of similar to0.04 cm(-1) is reported. (C) 2001 American Institute of Physics.
