Quantumcascade laser spectroscopy

All plants absorb light radiation nearby to grow, with no differentiation between a natural source such as the sun or artificial sources such as LED lighting. Plants have evolved millions of years under sunlight and are able to absorb most of the wavelengths present. They derive most of their energy between 400 and 700 nm. This is called the PAR (Photosynthetically Active Radiation) spectrum, which has become the standard measurement for horticulture. (Link to article 1)

If we take a closer look at this phenomenon, we notice that plants absorb light in two distinct forms: photosynthetic light and photosignaltic light.

All our special effects are controlled using our Fountain Studio™ and Fountains Simulator™ software that have been specifically designed to operate with unparalleled precision and speed our control towers and ultimately, our special aquatic effects.

In reality, not all wavelengths in the PAR spectrum are absorbed in the same way. This has been highlighted by Mc Cree’s work that characterizes photosynthetic activity as a function of each wavelength.

We draw your attention to the fact that this Mc Cree absorption curve is only an indicator. In reality, light absorption varies according to the species and stage of development of the plant. In some cases, light intensity can even saturate certain photoreceptors and change this absorption spectrum.

All of our aquatic special effects and laser projectorss are designed, developed and produced in-house. Our R&D (Research and Development) department strives to constantly innovate and maintain state-of-the-art equipment. All our special effects are controlled using our Fountain Studio™ and Fountains Simulator™ software that have been specifically designed to operate with unparalleled precision and speed our fountain controllers and ultimately, our special aquatic effects.

At Laser Quantum, we are a state-of-the-art designer and manufacturer of aquatic and laser special effects available for rental or purchase. We are also pleased to offer a turnkey multimedia show production service.

The quality of the spectrum received by the plant affects its growth rate, appearance and hormonal reactions. A spectrum adapted to your crops will always allow you to optimize energy consumption as well as the yields and quality of your productions.

• Red light between 570 and 700 nm is the most absorbed, with a major absorption peak at 660 nm for chlorophyll A and 645 nm for chlorophyll B.
