The photosensitivity of a fibre doped with GeO{sub 2} with a molar concentration of 97% is studied in the near-UV region. It is found that the refractive index induced in this fibre exposed to low-intensity (150 W cm{sup 2}) radiation at wavelengths of 305.5 and 333.6 nm achieves a high value ({approx}1.5x10{sup 3}). It is shown that the photosensitivity increases with decreasing the irradiation wavelength. (optical fibres and waveguides)
