Chinese laser pointer question.

Well, at least it comes with a "colorful box"! ;)

HAHAHA! Yeah. Mine doesn't even come with the ever-so exciting colorful box. Just the lame laser in all its glory. . .
Gotta be more powerful than a 301, right?

EDIT: Also!

I was also wondering if when I get it/them If I could potentially send it to someone who has an LPM to check the power, and they send it back to me after they measure the power?
If not, it's totally cool, but still a suggestion/question. Thanks everyone for your time!

I'm in western Washington, so not that far from you. I can measure power and wavelength as long as you pay the shipping.

AWESOME! Thanks a bunch bud! I am probably down to do that after I receive 1. The lasers and 2. The money.
I really appreciate your help. I don't often have cash, but if I come across more again or if I am finally approved for SSI(my hearing is in January)
I am really glad someone is down to do that, that quickly after I posted it. Thanks again!
 
Thanks, guys. It is of note that though the main line for these Nd:YVO4/KTP lasers is 532.14nm, it isn't the only possible line. Among the other possible lines are 538nm, 543nm and 546nm. I have two lasers doing multiple lines. One has four and the other one has six!

Wait, 532 DPSS have multiple lines? o_O
 
They can have multiple lines. They may also lase at another line besides 532nm. That was my only point.

Interesting. What exactly do you mean, multiple lines?
 
Lines are just wavelengths. You should get a diffraction grating so you can see how they work. You can get one for as little as a dollar on eBay. One of my multi-line 532nm lasers shown through a grating splits the wavelengths into individual spots that you can see and count. The spectrometers we use have mirrored or holographic gratings in them that are collimated and spread across a CCD or CMOS detector that can then give you a spectrum output that shows the wavelength and relative intensity of all the lines in that particular shot. On the cheaper 532nm pointers it is possible to find a multi-line output, but you can only see that with a grating or spectrometer. I have a sheet of 1 um line width or 1000 lines/mm. I got it years ago before I bought my spectrometer. Can't remember what I paid for it, but it was ~12 inches by 18 inches. I have sent many sheets out to people here so it is smaller now.

Would star cap gratings also show the presence of multiple 532 lines?
 
No. They are two diffraction gratings that are rotated against each other to get that effect. You need a single line grating. My preference is 1000 lines/mm. There are also many different types of gratings depending on the effect you want to get. Star caps are useless IMO.

Thanks Paul. What do the lines/mm dictate? What would be the use cases?
 
Diffraction gratings used to separate light are made up of lines on a mirrored surface or on a piece of glass or plastic that you use, sort of, like a prism to separate the light. You can get these kinds of gratings in different lines/mm. Like 300 lines per millimeter, 500 l/mm, 1200 l/mm, etc. For a loose grating used for this purpose, I prefer 1000 l/mm.

Alright! Finally I found one similar looking to the 532nm I ordered at somewhere aside from later images on a page on Wish.
Still not very informative(no description) and VERY full of misinformation(like 30,000mW, which Ifound HILARIOUS) found it on HTPOW (which I hear horrible thing about) but again, I'm not expecting an awesome (or even good) laser, but I am just curious, now that on have found another page with it, if anyone could tell me more about it. Would it be appropriate to subtract 2 of the zeros? I heard other people after I searched LPF for more about HTPOW to subtract one of the zeros, but I still think that is WAYYYYY absurd, so 2 may be more appropriate(300mW). I am not really expecting it to be anywhere over 100mW but I would be stoked if it did end up having a bit more power? They are trying to sell it for a laughable $846.18
So anyways, thanks for your time, any new information you can find on this laser would be much appreciated.

P.S. Is there a photo gallery anywhere on this site where I can search around and try and find more photos and descriptions of it?
