Potential new applications of synchrotron radiation based on stimulated emission from the target

While naively laser only excites target, it can also cause its deexcitation – as stimulated emission, ASE (amplified spontaneous emission), SASE (self-amplified spontaneous emission), synchrotron self-absorption, or in Rabi cycle cyclically causing excitation and deexcitation. STED microscopy is a popular application of laser causing deexcitation - I would like to propose and discuss a few more, based on its properties suggested by CPT symmetry, with potential realization by lasers or synchrotron radiation. For example, while CT scanner makes 3D maps of absorption coefficient, CPT symmetry suggests how to analogously measure/map emission coefficients, what should have much better transparency thanks to lower concentrations (N2 << N1). Related medical application could be causing deexcitation of autoluminescent molecules like NADH e.g. to starve cancer tissue. I will also propose a new type of camera/telescope, which should see synchrotron but not thermal radiation. I will also talk about the original motivation: more symmetric and powerful two-way quantum computers (2WQC), for example with photonic chip between coupled laser resonators.
