在我们实验室用能量为80keV的脉冲激光进行的几项研究中，已经报道了超高密度重氢D(-1)的核聚变。假设各向同性光子发射，在0.13J的脉冲能量下，每次激光产生的总电荷高达2μC或1×10~(13)个光电子。对于某些体系，光电子电流随激光强度的变化比线性变化更快，这预示着快速接近体积点火。在约1T的永磁体上，激光诱导过程存在一个激光脉冲能量阈值，这可能是由于D(-1)的大多数团簇在磁场中漂浮所致。这种迈斯纳效应之前就有过报道。
Nuclear fusion in ultra-dense deuterium D(-1) has been reported from our laboratory in a few studies using pulsed lasers with energy 80 keV. The total charge created is up to 2 μC or 1 × 1013 photoelectrons per laser shot at 0.13 J pulse energy, assuming isotropic photon emission. The variation of the photoelectron current with laser intensity is faster than linear for some systems, which indicates rapid approach to volume ignition. On a permanent magnet at approximately 1 T, a laser pulse-energy threshold exists for the laser-induced processes probably due to the floating of most clusters of D(-1) in the magnetic field. This Meissner effect was reported previously.
