For the Development of Femto Second X-Ray Laser Using Inner-Shell L23M1 Transition in Ca

A new physical scheme for femto second X‐ray lasers, where the upper lasing is pumped by X‐ray photons and the lower lasing level is depopulated via a Coster‐Kronig radiationless transition, is analyzed for Ca. The transition wave length is 4.1 nm, which is in side the water window. The peak spectra...

Description
Summary:A new physical scheme for femto second X‐ray lasers, where the upper lasing is pumped by X‐ray photons and the lower lasing level is depopulated via a Coster‐Kronig radiationless transition, is analyzed for Ca. The transition wave length is 4.1 nm, which is in side the water window. The peak spectral brightness of the X‐ray laser out put at 4.1 nm is predicted to be as large as 5× 1025 photons/sec./(mm2 mrad2 0.1% band width), which is 4 to 5 orders of magnitude brighter than a typical undulator radiation in the similar spectral region. In addition to the high flux, the expected duration of X‐ray lasing of ∼3 fs. will be useful for the study of fast dynamics in physical and biological sciences.
