Diode pumped night light?

So today on some spur of the moment thought I decided to make some laser dye with highlighter juice and isopropyl alcohol. I used my band saw to cut some acrylic for containing the dye, however, the hot glue-sealing operation got so messy I probably didn't need to make such a fuss over it.

Here is the dye cell with dye in it.


I started by pumping it with a 532nm green from a projector I made a while ago, but for a few reasons, I didn't get as much light production as I wanted.
This gave me an idea, What if it becomes a diode-pumped, dye night light?

So here is the final product, it is battery powered so I wouldn't really use it as a night light, but my cat seemed to like it while it ran.

You need to copy the direct link to the image, not to the Google Drive page.

On Firefox you can right click the image and select "copy image location".

Noooo! Not Photobucket, in time they will shut down third party hosting on you, if not already paying their ransom.

Surely you can come up with a better container. Something like these would be less of an eye sore:

Those would look quite cool with a dye sitting glowing in them actually.

I was going to suggest something more like this.

Still, that thrown together acrylic container does the job in a pinch to test out the idea.

Also, for the love of god stop using Photobucket. Try out Imgur, it's much better.

For those who can't see the images - there are chrome and Firefox extensions that force the images to load

(Technically the way it works is it spoofs where you're requesting the image from and say it's from their own site, so they let it load)

I considered using the glass bulb from an incandescent light bulb, similar to what you suggest. This project was just a fun thing to keep me entertained on a monday afternoon.

Yes, getting things to fluoresce can be a lot of fun. If you are just trying to get fluorescence, try a 405nm laser. They can be cheap to buy and will get any fluorescent material to light up brightly.

Will do, I do really enjoy lighting stuff up so it could be a fun project :)

Sounds like good fun, and a 405 nm diode would be ideal has a pump. If you mount it close to the dye container it'll probably be fine without a lens or anything. You could also UV led's to do the same, which are more efficient at low power but less efficient at high power.

I like the idea of using different dies though, you can make a light any colour you could this way, possibly better than you could using RGB led's as you can make actual yellow.

It's probably not gonna be the ultimate lamp, but could make for very nice decorative lamps.

Oh haha I do apologize for that, at the time I hadn't realized you need a quote to actually respond to someone. That was meant to be a response to Cyparagons excellent suggestion. Ill make sure to keep using quotes now thanks. :)

You are getting closer to correct--posts do not require a quote--
maybe this will help:)

if you come to a thread and see, say-- 4 posts you want to reply to... either use the 'multi-quote' then 'quote for the last one.. or copypasta- then your new post will have all the quotes & you can reply under each one or all in one post. There are exceptions to the no doubles 'rule' --most often its a B, S, or T thread and the OP is posting (again) to bump his thread towards the top-- and draw more readers-- no limit to those posts.. :D

...but once the item is sold we do appreciate that the OP edits the title (can only be done in 'go advance'.... btw please use edit and fix that & any other doubles you have posted.:thanks:

One other time would be a thread that is old but still relevent and the last post belongs to someone w/ new info to add-- that way those who have subbed the thread will get a nota about a new post--likewise tho..

. never post in a long dead thread unless you have a valid reason--check the date don't 'necro-post' if the thread is too old. :tsk:

In some cases you need to read more of the last posts--just in case another member necro-posted and any additional (necro)posts only complicate the problem.

Any member can ask a mod to close his thread or another's thread is there exists a good reason. That is REQUIRED if you want to start a new thread on the same topic as another thread or if it is placed in the wrong section you can ask for it to be re-located
PM me or any Vet for more questions & answers.

(now about your profile.......):shhh::shhh:
