  In the past few years, the search for axion-like particles (ALPs) has grown
significantly due to their potential to account for the total abundance of the
cold dark matter (CDM) in the universe. The coupling between ALPs and photons
allows the spontaneous decay of ALPs into pairs of photons. For ALPs condensed
in CDM halos around galaxies, the stimulated decay of ALPs is also possible. In
this work, we examine the detectability of the radio emissions produced from
this process with forthcoming radio telescopes such as the Square Kilometer
Array (SKA) and MeerKAT. Our results, using recent more realistic sensitivity
estimates, show that previous non-observation upper-limits projected for the
SKA were highly optimistic, with the limits from dwarf galaxy observations
being weakened by an order of magnitude at least. Notably, our results also
depend far more strongly on ALP mass than previously, due to the inclusion of
frequency dependent degradation effects. We show that the strongest potential
environment to probe ALPs is nearby radio galaxies (due to the strong photon
enhancement factor). In addition, with the use of a visibility taper, ALPs in
the mass range of $4.96 \times 10^{-7} \ \text{--} \ 1.04 \times 10^{-4} \ {\rm
eV}$ would have non-observation upper limits on the ALP-photon $g_{a\gamma}$ in
the range of $1.83 \times 10^{-12} \ \text{--} \ 7.69 \times 10^{-10} \ {\rm
GeV}^{-1}$ with SKA. MeerKAT can only produce limits similar to the CAST
experiment within 50 hours of observation. Finally, we demonstrate that
magnetic conversion of CDM ALPs to photons, in galactic magnetic fields, is
highly sub-dominant, even to spontaneous decay.
