摘要：

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 YBa2Cu3Oy, using a space/time-resolved optical transmittance measurement. The average velocities of the nonradiative fragments (2 x 10(5) cm/s and 2 x 10(4) cm/s) are much lower than those of the radiative fragments (5 x 10(6) cm/s and 1 x 10(6) cm/s). The yield of the nonradiative fragments increases with increasing laser wavelength, while that of the radiative fragments is nearly wavelength independent.
