Hello RIU Brothers:
I'm currently engaged in research on supplementing grow lighting with red and blue lasers. Take a look at this article I found on ISHS's website:
ISHS Acta Horticulturae 580: IV International ISHS Symposium on Artificial Lighting GROWTH OF RICE PLANTS UNDER RED LASER-DIODE LIGHT SUPPLEMENTED WITH BLUE LIGHT
Authors: A. Yamazaki, H. Tsuchiya, H. Miyajima, T. Honma, H. KanKeywords: Oryza sativa, laser diode, laser light, artificial light source, electrical-to-optical power conversion efficiencyAbstract:
As a new type of light source for plant production, high-power and high electrical-to-optical power conversion efficiency aluminium-gallium-indium-phosphor (AlGaInP) substrate laser-diode (LD) lamps with the continuous wave output power of 500 mW that have peak emission of 680 nm have been developed. To investigate the effect of red LD on plant growth, rice (Oryza sativa L. cv. Kitaibuki) plants were grown under the red LD light, with supplementing 5% blue fluorescent light. The result showed that rice plants could complete their life cycle under red LD light supplemented with blue light and they reached the harvesting stage earlier than control plants grown under high-pressure sodium (HPS) lamps. However, compared to the control plants, the rice plants grown under red LD light supplemented with blue light, showed 36% decrease in number of tiller spikes and 60% decrease in seed yield at final harvest. Rice plants can be grown using red LD light with supplemental blue light, but the system is new and requires further development and optimization.
This boil this article down, it appears to suggest that supplemental laser lighting could provide some real growing benefits!

1. Does anyone have any knowledge, experience and/or expertise on this?
2. Does anyone have any thoughts or ideas regardless of experience.
3. Can anyone assist me in figuring out how to take a single laster beam and manipulate it so it can be spread out over a conopy.
4. How could one take 4 laster pointers and convert them from "watch batteries" to AC power.
Now as far as question #3, I have had some decent success in dispersing the laser light by reflecting it off of a redbull can, lol. Just below the top of the can it bends out (curves) and then formes the body of the can. By shining my laser pointer just right I can creat a modestly dense pattern of light with almost a 12 inch diameter. With three or four lasers pointed form different angles would make a pretty dense pattern.
Here is a good link to a company that deal in LD (Laser Diode) lamps/lights.

Any sort of input on this post would be greatly appreciated.
