Here are a couple materials I have that shine a very nice red when hit with 532nm green laser. First is a lovely synthetic ruby that fluoresces very brightly, then a green laser target which contains a phosphorescent material (keeps shining red after laser is gone up to 5 minutes!) which is...

You're right, I didn't notice that. Both cheap in my opinion anyway. I was wondering exactly the same thing... My guess is yes.

I just noticed this one in the "New Arrivals" section (I thought I'd bump this thread rather than open a new thread on DX): DealExtreme: $39.66 Focusable 200mW Red Laser Pointer (1*18650) Yet another 200mW model, this one runs on 18650 Li-Ion (bigger than the previous 3 models) and is water...

Hey, I'm not sure if it was posted already (tried to search it), but I just noticed that DealExtreme dropped the price on the famous "Dilda" 200mW laser from about $43 to $29.53 (and shipping is free), perhaps because of competition? (o-like?) As an owner of 3 of those and a LPM, I can say...

If the "cons" don't bother you, then yes I recommend it, you won't be disappointed with the color of the dot. I tried making a picture of the dot, but it didn't come out very good, I'll try again with the help of my personal photographer (girlfriend).

Not yellow enough... See my previous reply. It was $350 without shipping and customs (I'll update the review).

There is one night shot already in the review, however I'm not getting the best results with my camera. As I wrote - the night beam isn't too impressive anyway as it looks almost like green, because the red isn't visible enough (I think because it's too wide). I will however obtain soon a fog...

Hey All, Here's my review of the CNI PGL-RG laser - a portable laser that includes both red and green lasers which are combined with optics into a single yellow laser. I'll start with this picture: Purchase: - Got it in one of the CNI group buys arranged by Glenn (along with 10x beam...

Correct me if I'm wrong - but isn't this photo made with short-wave UV? I have lots of those minerals, and most of them don't react to long-wave UV / BluRay. I wish I had a short-wave UV laser (instead of just a lamp)..... Beautiful collection BTW. I hope to post some photos of mine soon, not...

I have a Spartan BP20, back then the prices were higher and it cost me $799 like the 40mW they now offer... It's a very nice laser, I like it a lot. The beam is indeed not ideal in the Spartan BP, and the mode sometime hops to TEM01, but it really isn't noticeable unless you look for it. As...

Wow, look how close to the kid's eye the red "dragonlasers pulsar 125" (?) hits. Poor kid for having such a parent...

Hey, After having a green laser pointer for almost two years, I just noticed something very nice, which I never read about in the forum, so I thought I'd post it. I knew about freckles before, I've seen it on walls many times, but this effect is amazing: 1. Turn off lights (including monitor...

That's very interesting, thanks. But did you mean higher in nm perhaps (lower in frequency)? Because lower nm than UV is invisible to humans unless I'm wrong, and for example Uranium Glass under UV makes a yellow-green color which is from what I understand around 520-570nm. Higher nm than IR...

Hello, Does anyone have experience with IR lasers and know of any crystals or other materials that are fluorescent under IR? I'm getting a bunch of crystals of many kinds and I already have 405, 473, 532 and 650nm lasers, and I'm thinking of buying an IR. I'm checking Dragon Lasers, they have...

Re: Review Recopilation - All reviews in just one thread! Hey Niko, This thread is a great idea, the best way for doing some research before buying a laser (screw the "Search" button!). I would be glad to have my two (so far, more to come...) reviews in it: CNI green 500mw (I believe I will...

Indeed, I can't wait to get it (I ordered the 150mw for the best yellow color)... I promise I'll post a good review for it after I got it, with lots of info and especially multimedia.

Obviously the monitor can't produce coherent light for each wavelength, but correct me if I'm wrong - our eyes only tell between 3 different colors (RGB receptors) and all other colors are due to two or more of our receptor types reacting to the light. 405nm triggers some response in the red...

Hey, I was looking into a small on-line demo tool to show for which wavelength what the color looks like, so I can imagine how such lasers would look like. Spectrum drawings are plentiful, but I wanted a tool that I can select a specific wavelength and get its color in a big painted area...

Hey, I've had these 200 Uranium glass pieces for a while now (got them in eBay for $9.99), and finally got to making photos and videos of them with lasers. The natural color of this glass (under white light) is a "sickly" green/yellow color, and under laser light it's different. They are very...

I'm going to order it in this group buy, and then post a review of it.
