Lasing without Inversion in He-like Boron: Transient Response*

Lasing without population is more attractive in short wavelength spectral regimes, as traditional lasing condition are difficult to achieve due to fast spontaneous life time for shorter spectral domain. We thus here propose a scheme for demonstration of lasing without inversion in short wavelength regime. Using Helium-like Boron as our gain medium, we show that it is possible to have transient lasing with out inversion at 6.1nm.
