Project TitleA Laser-Based Illumination Technology for Indoor Horticulture Applications
Track Code2014-064
Short Description

Horticulture activities rely heavily on two important resources: light and water. Artificial lighting technologies are particularly useful in countries with limited sunlight and rainfall. In arid regions such as Saudi Arabia and the Middle East, over 95 percent of water can be lost through evaporation. Due to the scarcity of water in these regions, it is often necessary to cultivate plants in an enclosed environment, which can conserve water by up to 90 percent. Prof. Boon and his team at KAUST have developed a laserbased  illumination system for indoor plant cultivation that is both efficient and cost effective. The laser-based system replaces traditional fluorescent or LED technologies that are energy intensive and require constant monitoring for maintenance purposes. A single source of laser can potentially replace hundreds of fluorescent light tubes and LED lights.


The technology uses a laser-module that can be strategically directed at several rows of plants or crops in horticultural applications. The technology is scalable and validated in model plants (arabidopsis thaliana) that have shown positive growth compared to growth under white fluorescent light. The laser is high powered and can be tuned to produce the required intensity of light based on specific crops and plants. The laser panels and optics are based outside the horticulture chamber and are guided through access ports to the growth chambers in a single-tier or multi-tier plant cultivation setup.
