Default WTB Blue Laser able to spend around $100

what is the best offer i could get for this amount of money? i've read up on the blue laser (i say blue, but honestly it could be 405, 445, or blue ray i don't really care which). and i see some are pretty expensive, but those are very high power units, like 1W. i want something small, and semi-strong, like 300mw-700mw, focusable with a duty cycle of 60 or so... oh, and the $100 is just tentative, i could spend more or less depending on the offers

Edit: i'm am now willing to spend up to $150

Hello ryu037 and welcome to LPF. You can find several 445 (blue) lasers on the first page of posts in the BS&T section alone, and even more if you use the search button near the top of the page.

Be sure to check out this thread before buying or selling anything here, there is a lot of good info in there.

6 Steps To Prevent You From Getting SCAMMED

For $100 you won't find too many 445 lasers, but if you search around you may find some that are close to what you are looking for.

You didn't mention what part of the world you are in and that can made a big difference in prices due to shipping. Some that come to mind first though:

http://laserpointerforums.com/f39/1-...-us-63186.html

FS: 30mW 445nm pen

Please also consider buying some goggles that protect against the 445 wavelength with any purchase. Most of the 445 lasers sold here are class 4 lasers and they are VERY damaging to your vision.

yes i have kept all of those things in mind, but i'm new to actually posting stuff on the threads, so my info was lacking, i live in the southern part of TX. The thing is i don't want to build my own laser yet, i know i'm bound to screw it up, even with a kit... i was kinda hoping that someone would just sell me an old or unwanted unit of theirs hopefully around 500mw

I have a couple of fixed-focus lasers (~350mW) I would let you have for $100 each.

To get 500mW of focusable laser, you are looking at $150 minimum (unless you just get lucky )

Peace,
dave

That sounds really interesting, and from what i have read in this forum (it's been about a month since i have frequented here) you are an extremely reputable member, so i trust your laser, but i really want a focusable laser, even if it is not as high power, however, what kind of burning power can you get out of your 350mw?

350mW, especially focused for distance, is not a good "burner." These are best as a "pointer" or just to show the beam.

If you want to burn stuff, you are going to want that 500mW AND to be able to focus it up close.

Peace,
dave

thank you so much for the info Dave, it's mostly the details of the different powers that is obscure to me, one last question if you will indulge me. what is the difference between blue ray diodes and the 405 and 445 diodes. more specifically, what is a blue ray diode. and i have now changed the range of price to $150

Bluray and 405nm diodes are the same thing. Bluray is the "marketing" name that the DVD industry decided on for 405nm laser light. 405nm is violet. It is right at the edge of Ultra-Violet. As such, it burns better but is also much harder to see. Also, being right on the edge of UV, it causes many things to fluoresce. The present 405nm diodes can reach ~700mW (thought most run them lower than this).

445nm is blue. It is closer to our eyes more sensitive range. It is much easier to see. The 445nm diodes can reach 1.8W (though most run them lower than this)

Peace,
dave
