50mw Green laser Flash Light style no IR

[AUSBEN]

Hey i got a 50mw green laser pointer a day ago.


Its AWESOME! shoots stars everything. Can see it AGES away.


Anyway i was testing IR with my camera. There was IR. just wondering could a 50mw green laser with no IR do damage like real bad. I swiped my eyes one time times by Accident. But there was no damage to my eyes.


Laser pops baloons (Black) puts a hole through a rubbish bag but doesnt light a match

But its so powerful. When i take my dog for a walk. Ill show you the beam etc.



Pictures,

Excuse the little mess X:

[TTerbo]

Yeah i remember

I remember when I used to think 50mW of 532nm was "cool", lol. Nowadays I would be trading the old 50mW for a HeNe......
Give it time, if you stay with this hobby for a while, soon you will find yourself wanting a HeNe after all. When I was new I didnt understand the whole gas thing either, now I prefer them(HeNe) to diodes or DPSS, lol.
You must admit, this looks awesome:

Green lasers are very unstable and subjacent to temperature changes.
Try cooling your laser, like when you are outside on winter time, you will see that first ignition of laser - takes a while for it to "warm up" to working temperature, you see the crystal inside the laser, KTP, is actually named to work at 80°C, naturaly when you cool it - it won't work.
Heat from the diode will eventually get it to working temperature, but it takes time.
Such behaviour is normal in green lasers, don't worry about it

 

[AUSBEN]

ah cool thanks!.
