The April 2009 edition of Nature Photonics features an article focussing upon developments in liquid crystal lasing, and highlights simultaneous polychromatic lasing work carried out by COSMOS researchers. The article was written in response to a recent COSMOS publication in Optics Express on the same subject.

The January 2009 edition of Laser Focus World features an article highlighting research by COSMOS members on polychromatic liquid crystal lasers. The article was written in response to a recent COSMOS publication in Optics Express on the same subject.

The October 2008 edition of Nature Photonics features an article on the recent workshop on "Light Controlled Liquid Crystalline Complex Adaptive Materials" (LC2CAM). In particular, it highlights research presented at the conference by COSMOS researchers on liquid crystal lasers.

The COSMOS Research Showcase Event took place on Thursday 19th June, 2008. Please follow link for further downloadable information.
