Both on-axis and conical emissions have been observed following two-photon pumping of the 5p states of krypton and the 6p{prime}, 7p, 8p, and 4f states of xenon. In the former case, coherent emissions from the 5p states to the 5s are observed and in the latter case, many p {r arrow} s, d {r arrow} p, and f {r arrow} d cascade emissions are observed. By analogy to the well-studied alkali and alkaline earth examples, the emissions are discussed in terms of amplified spontaneous emission (ASE), stimulated hyper-Raman scattering, and parametric four-wave mixing. The physical processes responsible for the conical emission and for intensity anomalies in the xenon p {r arrow} s emissions are not understood at present. Interference effects due to coherent cancellation between competing excitation pathways may be occurring.
