We propose an effective scheme to enhance the efficiency of optical second-order sideband (OSS) via optomechanically induced absorption (OMIA) in a double-cavity optomechanical system. In this double-cavity optomechanical configuration. the optomechanical cavity is driven by a strong control field and a weak probe pulse. while the assisted cavity is excited by another strong control f... https://www.kingarte.com/product-category/dog-mess-cleaner/
