Can i burn something with it....???
Suntop | Aug 5,2014 at 02:25 AM
Hay Rahul.iub, if you need a burning laser ..... Buy a Samsung DVD writer and open it !

You will find a high power (Red & IR combined) Laser Diode

There would be 3 pins on it
(CD,DVD & Ground)

CD pin for IR (max 2.2 V)
DVD pin for RED (max 3.2 V)

You would need to gather Collimator & Optics (Lens) from other sources ( maybe form a cheap laser- that's what I did)

Also, make a current limiter circuit to drive or current will keep increasing when Laser Diode heats up and eventually avalanche breakdown will occur !

Good Luck !

P/S: I burnt a lot of matches in 3-4 seconds and was able to lit 2 cigarettes with lots of difficulties & my one died when I applied 4V to lit the 3 cigarette !

One more thing :


to see IR use your cellphone camera at a hither angle or use this IR Receiver Diode

it will give 0.7-0.8 volts when IR is shine upon it !

where can I get collinlmator n optics lens
Suntop | Jul 31,2014 at 12:48 PM
What's the lifetime of the laser diode ?

How many hours of continues runtime before it fails ?

Is it better than those 50 taka toy laser-key-chains ?
Suntop | Aug 5,2014 at 02:32 AM
Vai answer dan na kano ?
Suntop | Aug 5,2014 at 02:16 AM
Since techshopbd didn't respond to my query, so I just bought a Green laser form other source @1300 taka.

Don't konw what's wrong, why they are too moody to respond.

I think you should understand that our office just opened 2 days back and we had other works on hand too. We give more priorities to the queries we receive through mail. And sorry, apart from the docs and product page links given here, we have no other info. If anything is not written in these docs, it means that we don't know the answer either unless anything is written on the product's body or packet.
Suntop | Aug 5,2014 at 10:04 PM
I understand.... Thank You
Suntop | Aug 10,2014 at 10:50 PM
Just bough one ! It's kind of like the laser beam you will see on price tag scanner/barcode scanner used in super shops.

Better than toy lasers available in local market.

Because this one actually has an automatic power controller and photodiode feedback which I can assure you because I disassembled it to check.

So brightness is almost constant within operating voltage range for any voltage .

Operating at low voltage such as 3 volt it draws current around 28.7 mA and at 4.5 volt it draws 18.9 mA due to APC which maintains the power level nearly the same .

You can't get a DOT from this laser only LINE and by focusing the width of the line can be varied, not lenght .

The projection angle of the line beam is 100 degrees. Tough metal body also keeps laser diode cool, I am expecting a longer life from this laser.

Typical application : leveling, measuring height, security or simply exlporing it.
Suntop | Aug 13,2014 at 06:26 PM
Correction/Updates :

Do make DOT instead of line,

First unscrew the focusable lens. Now hold the metal front firmly & `twist the black plastic thread in counter clockwise to unscrew it. You you can remove the line lens . Put back the black plastic and screw to adjust focus to get DOT light .

Please let me know does it points as a straight line? And what is the operating voltage of the laser?
FAHIM_REAZA | May 2,2016 at 12:03 PM
>>Yes, its light emitted into a focal point.
>>Working voltage: Min 2.3VDC, Typical 4.5VDC, Max 8.0VDC.

Hi, can you provide us 1W or 2W laser diode for making a wood engraver!!
Sakkhor111 | Mar 30,2017 at 04:27 PM
I bought this but after receiving the delivery it was not as same as the picture. It was only a normal diode!
