Liquid-crystal lasers (2010, unknown): “…a variety of different liquid-crystal structures and phases: the chiral smectic phase 11,12 , polymeric liquid-crystals 13–17 , cholesteric elastomers 18 , cholesteric glasses 19,20 , an intermediate phase between the chiral nematic phase and the smectic A phase 21 , and blue phase i and ii 22–24 .”
A Brief Review of Stimulus-active Polymers Responsive to Thermal, Light, Magnetic, Electric, and Water/Solvent Stimuli (2010, background): “Ikeda’s group (Ikeda et al., 2003; Nakano et al., 2003; Yu et al., 2003, 2004a), Finkelmann’s group (Finkelmann et al., 2001; Finkelmann and Nishikawa, 2001), and Terentjev’s group (Hogan et al., 2002; Cviklinski et al., 2002; Warner and Terentjev, 2003) have prepared a number of light-active…”
Tuned, driven, and active soft matter (2015, methodology): “As one specific example, liquid crystalline elastomers were used to experimentally demonstrate the possibility to construct mirrorless lasers of a wave-length that is tunable by mechanical deformations [42, 43].”
