Default 20W's of 532nm, wow!

Check this out:

https://www.ultralasers.com/proinfo....age=1&featured

Imagine how bright that crap must be, you'd probably be blinded just by looking at the dot on a white wall! My 2.8W unit is bright and dangerous enough but this thing?

What are your thoughts?

Brightness is a perception, and brightness increase does not work they way most people imagine it works

Brightness increase ≈ √(P2/P1)

So, a 20W 532nm is 2.8 times as bright as a 2.5W, √(20W/2.5W) = 2.828

LoL.

Regarding 1 W yellow and 20 W green? None of them - I would go for this: http://www.laserfocusworld.com/artic...guidestar.html

50 W version (or higher) of course.

http://www.laserfocusworld.com/artic...igh-power.html



I always wanted my own star.

However, I think I will be excited from my 473 nm 100 mW ordered for a while.

The reflection off of a streetlamp will leave you seeing spots for a while from a good 100ft away. Experienced that first hand with a Laserscope converted to show use.

That's the kind of power you want to use for projecting onto clouds.

For a little more than the $31.2k cost of a 20W 532nm, without any doubt I would rather have a CNI 1W, 589.159nm +/-0.001nm Laser Guide Star system.

How much more impressive than a bright 532nm beam or dot, overall, would it be to create a sodium beacon type guide star by energizing a layer of sodium atoms that is naturally present in the mesosphere at an altitude of around 90 kilometers? Energizing sodium atoms that then re-emit the laser light, producing a glowing artificial star. Unbelievable, awesome, amazing, and way beyond cool-- right?

Creation of an artifical star in the sky at 90,000 meters altitude with a yellow laser. Now THAT is what I call, pointing out a star in the sky!

I received a quote back in 2015 for a CNI Laser Guide Star (LGS) system HPL-589.159-Q/0.2~1.2mJ/1~6W LD PUMPED ALL-SOLID-STATE AOM Q-SWITCHED LASER with HPL-PSU and water chiller for cooling laser---complete system --price was not as high as I thought it might be.

The price of the lowest cost version, bottom of the range, including delivery within USA for 1 piece, CNI, HPL-589.159-Q/0.2~1.2mJ/1W with PSU and water chiller, 589nm +/- 0.001nm, < 10% stability, was $44,000.00.
