Time-of-flight mass spectra are recorded from the laser-initiated plasmas from solid YBa2Cu307_8 using combined 1064 and 532 nm laser light pulses of 10 ns duration. The effect of changing the laser power density was studied for both low masses and also for cluster ions ranging up to 20,000 amu. The cluster ions grow in intensity with increasing laser power densities until they abruptly vanish at plasma energies (temperatures of ~10 4 K) associated with a white plume visible with the unaided eye reaching ~1-2 cm above the target. Fewer molecules are found below 400 amu with increasing laser power densities, but some molecules still persist at the laser's highest intensity of 4.3 J/cm2.
