glad to see you're doing a lot of reading:beer:. keep it up and you will soon grasp the concepts involved in building your own laser. good choice on the driver - you will not Need to test it with the test load. be aware that the driver from survival lasers will need 2x 3.7V cells to deliver full...

Re: FS: 520 Green in SS Aurora Host i can also sell this laser with a 3 element lens for $175. this has the effect of reducing power output to 80+mW

Re: FS: 520 Green in SS Aurora Host yeah i know the feeling - i saw hwang21 had his argon up for sale when i wanted to list my argon. i'm glad his went quick so i could put mine up. anyway....it's not "exactly" like my 520. this here is a genuine cheech build. :wave: thanks for the kind words...

what diode?

Re: FS: 520 Green in SS Aurora Host i can always build another one. some can't or won't so..... besides, i need the cash. it is a jewel tho - thanks for the compliment

ok, i'll throw in an aw 2400mAh 18650 battery. you can own this laser for LESS than the cost of parts alone! also i can install a 3 element lens instead of the g2 and let it go for $175 plus $5 shipping up for sale is a great green laser in one of my favorite hosts. the aurora sh-032 is a very...

too frigging cool! pop a balloon and kill a zombie too ;-)

welcome! and please do take advantage of our wonderful search bar at the bottom of the page. it returns results exclusively from the Huge data base that is our forum. most every basic question a beginner could ask has been asked hundreds of times and all the answers are there.

a more powerful laser would probably do the trick as was said. as far as purchasing a submersible laser maybe a fiber coupled handheld would be better. i admit to knowing very little about fiber outputs and focusing. but if you could just submerge the end of the fiber the laser itself could be...

and just what are you planning on putting the batteries into? you will need to use 2 of them to get the required voltage for the driver you described. 18650's are long you have a few here willing to help you, but you must help us. some pictures of your driver will help a lot. if you plan on...

wow, i dig the host, good find. fine build man, looks like a keeper there.

beer sure is amazing stuff....:beer:

if you want a great buy on a green check out offroadfreak's skylasers group buy here http://laserpointerforums.com/f55/open-taking-orders-round-4-skylaser-laserbtb-groupbuy-86275.html last round i purchased the hl532 300. it is wildly overspec (>500mW) burns well, is focusable and has an...

why two threads for the same question??

could you tell by determining it's lasing threshold? i can't say for sure but i'd guess that in a 12x and a phr there would be a notable difference.

Re: Feeler: Osram PL TB450B 1.6W (Not M140) i'm surprised you got it to lase. the sheet says a threshold of 200mA

Re: FS: JDSU muliti line Ar ion all good guys....i've been known to do it myself on occasion. I think I have it sold. a member has expressed interest and we're working out details. i wll report back later today. SOLD

sad to say i must part with my argon. this is a jdsu 2214 ml40 cylindrical tube along with it's 2214 power supply. it produces 5 lines at idle (4A) and the 6th appears @4.2A. lines are blue to green with the 502nm line being the 6th. lines produced are 457, 476, 488, 496, 502, and 514. this is a...
