Laser Holograms With Prisms, Mirrors, Uranium Glass and Mica Pigments. (Humidifer Added).
I am doing some more laser projects with uranium glass, prisms, and mirrors. We can adjust the prisms in front of the lasers to get some different results. The unique part is the uranium glass that I am working with.
Normally, uranium glass isn't that dangerous unless it breaks into a fine dust; then you could inhale uranium, dust, which, with prolonged exposure, is dangerous. When used normally, it is considered safe.
We can do this simply with three 90-100 mw lasers (Red 660 nm, Green 532 nm, Violet 404 nm). Also some additional lasers Lime green laser 520 nm and cyan laser 488 nm can be used an an optional laser but are generally more expensive. I also have 1, 90 mw 445 nm to 450 nm blue laser that i use as well.
However, to keep it simple, we start with three lasers and add more if we need to. Some lasers are a bit weaker at 50-60 mW, not near 100 mW, but respect is still needed when working with lasers. This is to avoid indirect exposure or a direct hit from the lasers.
An special note that lasers should be directed flat 180 degrees on an table or at a 45-90 degree angle never have the laser anywhere you could get hit with be a few meters above the safe threshold of the laser beam.
We can also use a humidifier to put humidity and water vapour into the lasers and lens with a prism, but it is not as effective as a fog machine. It still works but requires special alignment of the moisture of the humidifier.
Note special laser goggles MUST be worn while working with these powerful lasers!

Operating a Laser Hologram With Prisms, Uranium Glass and Mirrors.
I got the idea to make a Uranium glass-based hologram with prisms by firing a 50 mw laser at Uranium glass 1 year ago. I thought, of what if i could expand this to make it colorful? I only have a few pieces left I sold a few to a friend for cash.
Uranium glass with lasers and Optics is very pretty and can be done by anyone who has these equipments see above in Supplies.
The prisms right in front of the lasers can be used to focus the lasers and change the beam direction, but this is dangerous if you don't wear goggles. Make sure you do this with safety goggles! By placing the lasers in front of the prisms and taking pictures, we can get different results.
We can put small bricks 1 cm by 4 cm over the lasers so they don't move a method of keeping the beam stable. The RGB lights are attached to light bulb holders and clamps.
The lasers that I am using range from 50 to 100 mw of optical power.
Weighing Out the Fluorescent Mica Pigments
Here we have 10 g of Mica fluorescent pigment which may contain formaldehyde phenolate compounds, so wear a mask to do this. Take some 200 ml plastic bottles with caps and add 2 grams of the powder with 200 ml of water with a few drops of vinegar.
Close the lids and shake them but wear full PPE in case anything spills (Gloves, apron, goggles, etc).
The mica pigments are very fluorescent under Green 532 nm lasers, Blue 445-450 nm lasers, violet 404 nm lasers and sometimes red and violet lasers with a prism that activates the fluorescent properties of these mica pigments.
For the pigments that cost 50 dollars, we add 2-3 grams in ethanol or isopropanol alcohol (70-99%) in glass bottles found on Amazon. 3 grams of powder mica pigments and 120 ml of alcohol.
Some pictures will be shown above of what they look like.
Final Results of Lasers and Uranium Glass Optics.
Here I explain what can happen if we have a humidifier and mica pigments. Please see the description and pictures for more details.
Although it can be difficult to do we let the humidity in the humidifier hit the lasers and prisms to be reflected onto the lasers and Optics themselves. This can take 5-10 minutes and the lasers can be run for 10-15 minutes with cooling (turn them off for 15-20 minutes) afterwards.
Conclusions of the Lasers and Optics
This is a nice project with uranium glass and optics (mirrors, prisms, etc). We can normally run the lasers for a max of 20 minutes, then turn them off to cool down. (20-25 minutes) to allow the laser module to cool off.
The combo of fluorescent pigment that are weighed out in a scale and put into a funnel and placed in bottles (Plastic and Glass) are a nice additon.
We need other mugs and 2 L and 1 L flask to get good results on the camera. The camera on your phone should pick up the different hues of the lasers. Never have the camera directly at the lasers it may destroy the CCD part of the camera; only indirectly is the camera safe with lasers.
