CMMPE has been performing extensive research into a new form of laser technology based on liquid crystals. They demonstrated a two-dimensional liquid crystal laser array, consisting of red, green and blue colours simultaneously being emitted from a single liquid crystal laser device, whilst being optically pumped with a single 430nm source. The article suggested that liquid crystal lasers could be used to replace the individual RGB lasers that are currently required in emerging laser displays. This would facilitate a reduction in the fabrication and materials cost of this currently fabrication-expensive technology. Furthermore, liquid crystal lasers are less likely to suffer from problems such as speckle, which are commonly associated with conventional laser display systems.
