Abstract：
Laser induced nuclear transitions between isomeric states were calculated by a parametrization approach.The effect of laser linewidth were taken into account.Based on the calculated transition probabilities,laser stimulated conversion from long to short lifetime states was studied.The kossibility of changing the lifetime of the long-lived isomers and developing gamma-ray laser is discussed.Numerical evaluations show that the laser intensity required to develop gamma-ray laser in this approach is higher than that available at nowdays technology.
