… a possible realization of the spaser 1 . Here we introduce a further development of the spaser
concept. We show that by combining the metamaterial and spaser ideas one can create a …

… of coherent radiation, the lasing spaser 10 . The key element of the lasing spaser is a plasmonic
… In this letter we propose a lasing spaser that is fueled by previously overlooked toroidal …

… lasing device, the “lasing spaser”, a metamaterial version of the spaser [12]. In this paper for
the first time we demonstrate experimentally that hybridization of a metamaterial with a layer of …

… is a periodic lattice (plasmonic crystal) of individual spasers that interact in the near field …
lasing spaser is a plasmonic crystal that incorporates a gain medium. One type of lasing spasers …

… stronger than that of the lasing nanoparticle sample. But … first experimental demonstration of
a spaser, which we report … of a spaser 3 and the more recent concept of a ‘lasing spaser’ 25 , …

… show any signs of lasing, which fact independently confirms the plasmonic nature of the
observed lasing (spasing). Being a thinnest (∼100 nm) laser, the lasing spaser 3 promises new …

… As an evidence of an optical lasing spaser above the threshold, we observed a sharp line
appearing at a wavelength of 520 nm (Figure 3c), which is significantly shifted from the center …

… of spasers and nanolasers. This is followed by an overview of crucial technological progress,
including lasing … and improvement of spasers, the array operation of spasers, and selected …

… a lasing regime associated with the formation of a dynamic vapour nanobubble around the
spaser that … The absorption losses in the spaser enhance its multifunctionality, allowing for …

… Yet another theoretical development has been a proposal of the lasing spaser [34], which
is made of a planar array of spasers. The theoretical publications mentioned above in this …
