【 摘 要 】

The effect of pair creation from the vacuum in a strong electric field, predicted by Schwinger in 1951, may conceivably be confirmed experimentally with some of the ultrastrong lasers presently under construction. However, it is not easy to calculate the effect for realistic laser fields. We will shortly review here the intermediate case of a purely time-dependent but otherwise generic electric field, which is still relatively amenable to calculation.
