I got a supposedly "<1mw" green laser pointer (same

>>7989163
Idk but how do I get one and how much does it cost?

>>7989176
Fleabay.

Protip. Don't aim the beam at a camera. Fucked my tablet up. Glad it's a work tab.

>>7989176
Like 4$ delivered

No help from laser bros?

>>7989163
nigga 1mw is nothing

lasers go up to 5mw are toys and safe and legal everywhere, they use it to point at shit in classrooms etc

yours is 5 times weaker

>>7989163
That's way more than 1 mW OP. That's fucking awesome. I'm guessing it's around 50-100 mW. You could make a laser power meter and test if you want exact numbers, but first where did you get it OP cause that's fucking awesome!

I have a samilar one i got off a chink site. Though its actually less than 1mW like it says. Not hot on skin, but does go very far.

>>7989163
first:it's normal, a laser doesn't go full power right away, it needs time to stabilize
second:if I remember correctly, the "1mW" means that a certain percentage of the laser pointers will deliver 1mW. It doesn't prevent the laser pointers from giving off more power. Also:

>yours is 5 times weaker
Clearly it isn't. It's supposed to be, but he's obviously got a much stronger model.

>>7990399
Yeah probably a fucked power regulator or shit housing.

Infrared hazards of diode-pumped solid-state laser pointers
Green laser light is generated from an infrared laser beam, which should be confined within the laser housing; however, more than 75% of the devices tested were found to emit infrared light in excess of the limit. (wikipedia)

>>7990817
What would be a good way of minimizing the escaped infrared light? Tape up the housing and put an IR filter over the lens?

Op here. This is the Item I got.

Am I in danger if I look at the point reflected off a matt surface, wall etc?

The particle discharge could be so great that it could fling you into the future to year A.D. 802,701

How do you make a power meter?

Does the fact that it made a contact thermometer read 50°c but won't light a match (red) give an indication of output?

>>7989163
protip: 1mW lasers from ebay are actually 300mW

yeah, it means that it's probably more than 5 mW or you live in a weird part of the universe where thermodynamics does not apply.

You can make a simple laser power meter from a piece of matte black coated aluminium foil and an IR thermometer:

Pic related. Thx for the link.

>>7991608
if the surface is really shiny, so shiny that it reflects into your eyes maybe. Basically don't point it at your eyes and consider purchasing some laser safety goggles.

>>7990841
Well you could just buy a laser pointer from a reputable source. Modifying a laser diode is really fucking difficult.

You got lucky OP, you got a high powered laser for cheap! It's worth keeping around for sure.

Ok, did this and got a reading of 113 mw!!

Somebody told me that green lasers work best against black matches. Coloured one in with a sharpie and yep, now it lights them easily from 6 inches.

Trouble is, I wanted it as a laser pointer but I don't want to blind colleagues. How much can I sell a 113 mw laser for?

>>7989163
What would happen if someone accidentally pointed it to someone's eyes? Permanent or temporary damage?

>>7993722
See my picture in >>7993605
That's the damage it did to my camera due to an accidental reflection. If that had hit my eye instead that would have been retinal scarring instead of camera damage.
