Abstract

In addition to the two groups of radiative fragments which have previously been described, two groups of nonradiative fragments are first observed in laser-ablated fragments of YBa₂Cu₃O_y, using a space/time-resolved optical transmittance measurement. The average velocities of the nonradiative fragments (2×10⁵ cm/s and 2×10⁴ cm/s) are much lower than those of the radiative fragments (5×10⁶ cm/s and 1×10⁶ cm/s). The yield of the nonradiative fragments increases with increasing laser wavelength, while that of the radiative fragments is nearly wavelength independent.
