Default Aliexpress 200mW green laser review

Hello, I decided to risk my money into a laser from Aliexpress, I expect at least > 50mW from it, so if it burn stuff I'll be happy.

THE STORE:

The store are located at this address 'http://www.aliexpress.com/store/1512025', soon as I bought the laser, all the products was excluded from the page, seems that the guy has shut down it Aliexpress account.

DESCRIPTION:

Since my product is now unavailable, I have access to a snapshot of it:

Quote:
Product Description
this is the newest model of a flashlight shaped green laser pointer torch, it is designed with a focusable lens, metal body.
Size: 14.5cm * 2.5cm
Wavelength: 405nm/543nm/650nm Blue&violet/ Green/Red
Range in darkness: 10,000 meters
Power Supply: 3.7V 18650 Industrial Package Li-ion Battery with multi-function charger
Focusable(you can change the size of the point)
Torch Color: Silver Black (leave message which want ,or random)
WHY I BOUGHT IT:

I know that is a chinese laser, I bought it because the host, I liked it, is different from the 301/303 lasers, if the laser stops to work I'll still have a cool host to use.

PACKING:

Not well packed, I perceived it immediately when the post man arrived, a simple yellow bag, the laser was inside a very tight bubble plastic, so if something had knocked it the laser could be damaged. Lucky, it arrived with no damage:





THE LASER:

The laser is very lightweight, the finishing has some defects but nothing critic, the host seems to be a copy of the OX-G40 laser:





The host is nice and comfortable, it have a big orange ON/OFF button that seems more robust than the lateral push buttons:



OUTPUT:

Since I don't have a LPM, I'll guess the output, > 50mW and < 75mW (yup, <200mW, so it a on spec laser ), the dot is clear and I don't noticed any mode hopping, TEM00.




Does it burn? Yes! I did some tests, I was able to burn electric tape and fire a match easily than my 303 did. I'm curious to know the real power/IR power of it.




SHIPPING:

The laser was shipped 19/01/2015 and arrived today, 19/03/2015, two months, a medium speed shipping here in Brazil.

Worth it? In my opinion, yes! The seller had 84% of positive feedback, and this laser didn't had any feedback, so I bought it blind wishing for the best. For me that use it only to point to stars and far objects is a very good laser, if I need do beam shots I'll go with high exposure, If I want enjoy the beam, just a bit of fog does the job.

CONS:

It could be shipped with something to put in the place of the kaleidoscopic diffraction grating, so dust don't go on the lens, as in the original image:



Of course, not close to 200mW, but feels like > 75mW, the kaleidoscopic diffraction grating is one of those generic seen in laser pens.

To protect the bare lens, I added a small plastic piece that should do the job.


HOST:

The host comes with two rubber rings, in the announce, it says that are waterproof rings, but I don't want to try it, here are some other images of it:






Here some additional requested info.

Focus range: From infinite to 3cm.
Beam diameter at the opening: 1mm.
Beam divergence: 2.5cm at 9.8m; 2,45mRad.
Input current: 440mA (measured with 1R resistor at tailcap).

After 5 minutes of continuous use, the host gets a little hot, from 26C (room temp) to 30C, the output was stable at TEM00 all the time.



That's my first review, so, sorry for something.

Default Re: Aliexpress 200mW green laser review

I had some click buton lasers, one was a green JD-850 (that arrived broken) and one is a purple GD-320 (for my mother), I need to get used to it, if not it can be very dangerous.

Comparing the output to the other green lasers I had, this is the brighter one. It doesn't burn too well, but the beam is more bright than all the other lasers I had. Maybe less IR more green? I'll post some beamshots at night.

Yeah some night beam pics would be great. Thanks for sharing this with us.

Focus range? Beam diameter? Beam divergence? Input current? Input voltage required for current regulation? Temp rise?

Why don't I see any numbers here?
