Help laser doesn't work!

[arton106]

ok so i bought this laser
TinyDeal - Android Smart Phone, LED Watch, China Online Shop, Free Shipping

i received today the package
at the first minute it worked well then i twisted something and the strength has been gone weaker and when i twist it back its just getting weaker
now when wait 10-15 minutes it does work for an second
than its gone

and when i look into the pointer i see an little red light shine

here is my video

please look at 0:09-0:12

maybe its the battery i don't know.

under $40 for 250mw green? that won't be up to spec

and that 'little red light shin' you looked in to may have been a huge amount of IR light that just damaged your eyes

looking in to ANY laser that is >1mw is a bad idea, if that's what you meant

you should get your eyes checked by an eye specialist immediately

As Magmabeam said, That "red light" is the IR pump diode and could be 500mW-1W of invisible IR. Do not look into it. I realize you already did, but I have to reiterate what Magmabeam said just to make sure you understand what you just did -- you stared into an operating high-powered infrared laser.

It sounds like the battery to me, but I'm no expert...

I'm just assuming here... (you know what that means)
but let me guess:
- It's a li-on battery
- you have no charger
??

Man, I got the willies when i saw that dim red dot.

You need to go get your eyes looked at pronto.

sorry to say this happened to my 100mW laser but your diode died

sorry to say this happened to my 100mW laser but your diode died

could i get it back to live you think?

 

[weeba2kv]

Sorry but it's dead , you could make it into an ir laser

 

[arton106]

can i still burn things?

 

[magmabeam]

possibly

have you checked if you burned your eye yet?

 

[arton106]

possibly

have you checked if you burned your eye yet?

how can i now i see the same
i only felt doay a bit dizzy more not

 

[australialaser]

could i get it back to live you think?

maybe if you get another 808nm laser diode and put it infront of those cystal maybe you could fix it

 

[Blade]

definitely get your eyes checked!

i once had a laser from focalprice that did the same thing. but i then turned down the pot and the 532 began to lase again. try turning down your pot if you can access it. but then again maybe it is totally dead...

FYI, he hasn't tested new batteries, and has no charger...

I've PMed him suggesting testing with new batteries and actually getting a charger.
