Now, I don't have the interest to grow plants in a very scientific way, compiling data for 4 years on pepper plants, but it would be interesting to see the effects of lasers on plant growth. There haven't been many studies on it published online.

Those are literally everything I could find on the subject.
Here's my serrano peppers (at least I think they are, I put a lot of different seeds in there because it's too cold to sprout anything). The one under the blue 420nm LED light was being irradiated for more than 24 hours before I found the second sprout, and started feeding it 650nm laser light. Not stating anything here as science because there's only 2 plants and everything I ever grew my whole life up until now died before growing up; I'm a terrible father

Here you can see that the first plant is pretty much starting to rot, but that started happening 2 days prior. You see I pulled up the seed because it's pretty much dead now and I was curious. This photo was taken 1 day after the first, with one reasonably long night cycle in between.

There's a great thesis in here somewhere. You could grow 5 plants per pot and shine on them with equal power under one laser, and grow 5 other plants in another pot and shine another wavelength on them, and then get groups with regular LEDs, then groups with incandescent lamps, and whatever. The experiment would take years. Maybe you could get plants to grow faster by saturating them with more light and increasing the frequency of light cycles. Maybe you can influence the plants to produce more chlorophyll a or b.
There's no way I would commit to it, but I will be growing some plants under lasers in a leisurely manner. I'll probably continue with this little 10mw 650nm, then grow more with a 405, 445, 635, and 680. This pepper looks like it's reacting nicely to my laser. Who needs sunlight anyway. I suspect I'd get less fruits if I continued with this one wavelength.
I guess I'll update the OP / add posts if I note anything interesting, in a completely non objective manner of course.
