摘要：

Transient absorption spectra of liquid selenium after illumination with a pulsed laser have been investigated. It was found that a giant photodarkening occurs and the optical gap disappears when the pulsed laser illuminates liquid selenium at 350 degrees C with the intensity of 15 mJ/pulse. The possibility of a photoinduced semiconductor-metal transition is discussed.
