摘要
研究了在相对论领域内，超强激光场的不同条件（频率、强度、脉冲波形磁场分量）对氘原子电离几率的影响，研究表明：电离几率随激光强度的增加而增加，随激光频率的增加而减少。而激光脉冲波形对电离几率的影响仅在激光无磁场分量时比较显著。激光场的磁场分量对原子的电离有一定的影响。
The effects of various laser conditions (fequency, intenstity. Pulss shape, magnetic component) on relatvistic ionization probability of deuterium are studied. The results show that the ionization probability is increased with increasing laser intensity. But it is reduced with the laser frequency increasing. The effect of laser pulse shape in no magnetic component is more ovbious than one in existing magnetic component of laser will give some influences atomic ionization probability.
