New member- 12,000mw blue laser?

[USAbro]

Try a cd case. My 1.6 watt can melt a hole from 18 feet. I haven't tried further but the beam start getting to big.

hmmm-I don't have a cd case- and my hotel room isn't very big...
but wow, it is burning the back of the black "no smoking" sign at about 10' away- I put my hand in front of the beam and it took less than 3 seconds for it to hurt. Think I need to recharge the batteries again.

haha- I'm burning the "no smoking" sign

(it still smells better than walking around hk!)

I actually sent wicked laser an email asking if I could swing buy to check out their inventory- they are only about 3 miles from my hotel- they responded pretty fast saying their business isn't open to walk-in traffic, mail order only and they could only guarantee delivery to my hotel within the next 9 days if I paid the expedite shipping fee! I'm only 3 miles away!!!

Where are you then?

Where are you then?

I'm at the regal hotel in kowloon, hk (70 mody road). I'm actually only about 1.5 miles from wicked lasers (3 miles round trip).

I fly home home on thursday- so if you want one, let me know

I've been to hk 4 times, japan twice and s.korea a3 times over the last 2 years- the only 2 times my bags were searched was returning to the states from japan- they made me lay every article out on the floor and turn every pocket inside out. right in front of the gate. they were very polite - they explained it was a random check
but I travel about 300,000 air miles / years so, I get searched now and then. never from HK or s.korea.
europe just always asks to see my passport 3 times before boarding.

This store I bought the laser at was somewhere near the hk side across the bay- I got the whole weekend to shop around- if you need something, just let me know. tons of powerful lasers around here. I may even be in your area in a week or two in working in some Maryland hospital.... I can get stuff in the mail on thursday,.. they had a 5000mw blue laser for around $65... I can try to find the store again tomorrow. she also has some larger laser boxes- for stronger lasers....

I'm starting to crash hard- it's 1:45am here in kowloon. check back tomorrow

12w will do a lot more than that. But still seems like a good deal for that power! These Chinese developers need to go easy on that potentiometer!

I'm guessing 2w<.

HaHa!

With these power ratings from Chinese mass produced laser, drop a zero off. So your 12,000mW would be 1.2W(1200mW), which is much closer to the actual power.

From the photos you posted, the host looks a bit small. At a power of 1.2-2W, no wonder it gets hot quick. I don't see it lasting long if it gets hot to the touch in less than 30s.

yeah- I would say dropping a zero is an accurate statement. It's funny because the box says class IIIA laser, but the sticker on the device says Class IIIb- lol
I'm far from being an expert on lasers but I'd guess this is somewhere in the 2+ watt range. neither class is correct for a 12w laser

After allowing the batteries to fully charge over night, this laser is burning my black cell phone case at 10'+ within a few seconds- and it'll burn a hole in white paper at 1' in about 2-3 seconds- I burnt a hole clean through the dark purple plastic water bottle cap in 2 seconds.

I'm going to head back to the store and see if I can grab a tri-pod and maybe some mirrors.

some of the spectrometers I work on use powerful lasers and have some nice heat-sinks. I have a bunch of spare parts back at the shop and I'm thinking I'll make a nice heat sink mount for the laser. I have a bridgeport mill and a large lathe at my house- so, I can do a nice job with it.

Congratulations and the new laser! Only thing I can think to add is that you may want to buy a new pair of safety glasses. I recommend the following:

Eagle Pair® 190-540nm Standard Laser Safety Goggles

A direct hit to the eye with a 1W laser can be devastating, and cause permanent eye damage, and possibly blindness. I recommend these glasses to anyone with >5mw. Take a look at these threads when you get a chance.

Thank you for the picture, and the review of this laser. Also, Welcome to LPF!

thanks nute

so- I completely dissembled the laser- there it was, as clear as can be, engraved on the inner cylinder "9/2014 1.7w blue" lol!
just a wee bit short of the 12,000mw on the sticker! chinese

still a fun laser

 

[USAbro]

Same with mine but mine is engraved 1.6 watt.

 

[Nute]

1.7 watts of 445nm sure is nice isn't it! Nice find!
