Latent antiphase dynamics of a multimode solid-state laser with intracavity SHG

Summary form only given. We report the first, we believe, experimental observation of such a kind of antiphase dynamics (AD) of a Nd:YAG solid-state laser with intracavity SHG, which can be referred to as a latent AD (LAD) since the modal pulsations do not display themself in sum, i.e., in total laser output.
