    Wink2 My First Greenie, what model is it ?

    Hello
    Can You tell me model/maker of this Laser ? I just odered by eBay.
    Any luck for modding this unit ?
    IMO it's bright, but I was thought that claimed 40mW should look brighter..

    Oh sorry, I didn't realize that product's box picture of laser line outdoors, was forbidded. I apologize for this.
    Try once more time:

    I need to know is this unit really more than 5mW ( claimed 40mW ).
    If this is low power unit I may use it to some fun for my cats.
    If it is more powerful, I need to buy goggels for safety.
    I have two times in my life very close to lose my eye sight. So I wanna play safe with this greenie.

    Just curious...
    How much was it and what kind of batteries does it take?

    Hahaha Re: My First Greenie, what model is it ?

    it kinda looks like the tin man from Wizard of OZ "if I only had a brain" while he shoots a laser out his head

    Hopefully you didnt sent too much like I did, paypay wont help. Mine was illegal sale. they dont care. This is a call mind you I made.

    Best go to the reputedable dealers.. I am not going to say anything from here. Read the forums and make your own conclusions. If you want a hig power cheap laser, maybe try waiting 3 yrs. Might be just like LCD TVS

    Im laughing because I got burnt and have learnt, lol. You can read my threads.
    In allseriousness though, if you want to get your money back you will have to send it with a signature required after doing a item significantly not as described on paypal. Its your decision whether or not its worth the loss of the shipping costs. Ebay is a sham. I have even tryied to report stuff that i had stolen and possible saw there. they dont care.

    Noboydy knows, specs for this laser ?
    Picture of beam has little help by steam.

    Body style is similar to the Novophone, but I don't think they sell a chrome model. Also, I think they have a rubber button. Is there any info on the laser or box that would lead to a manufacturer? Link to or ebay auction # might help as well.

    Is that picture in your second post the box in which the laser arrived? If so the laser on the box is much different from the laser you received?

    Anyway it looks like a Novophone model, it's at least similar as it has the exact style casing save that it's metal/chrome. I've heard these are quite hard to take apart without using a can opener, meaning you will probably wreck the casing trying to get it apart.

    As for output, it's hard to say. Does it make holes in black bin liners? A 40mW laser should do that. At any rate even if it's just 5mW, it will still be to much to use as a pet toy. I'd not suggest using anything higher then 1-2mW for pets.

    Hello
    The Laser came with above box.
    I just received rcr2 cell from AW and now its full charged;
    Laser will make tiny tiny holes to black vinyl bag, distance was less, than 1 cm and about 6 seconds or so hole came.
    It won't light match, won't burn fingers, takes 220mA juice.
    eBay seller was person, not shop and it was only piece in sale.

    It's up to you, just be ready to accept the outcome. Maybe you'll get a good gain, maybe your laser will die immediately or very quickly. Only one way to find out..... .

    If you do mod, you might want to check the current draw before and after modding. If nothing else, it will give you a starting point so you can turn the pot back down to the original point.

    Question Re: My First Greenie, what model is it ?

    What now ? :
    I managed adjust pot and 220-->270mA, then no more green laser light, only red glow. I did not look direct to laser. Still I can adjust amperes of laser and I did noticed with my camera + ir filter, that there is ir light caming out of laser.
    What happened ? Burn my laser diode ( how come it still take amperes and it could be adjusted by pot ) ?
    Please, gimme info somebody !

    Turn the pot back down for starters. Hopefully you did not touch the screwdriver to the casing and pot with the batteries installed. Post results.

    I do have ceramic pot screwdrivers. I did turn it back to 220mA, but still red glow.
    I found way to open partially lasers case.

    I wouldn't think 270mA would be overdriving by any means, if it is in fact a 40 mW. I was trying to read the back of the box you have posted, is 40 mW even listed? Also, you say that the laser is currently emitting IR? Is there an IR filter present? Protect your eyes. You may have been getting 40 mW total power, with IR accounting for most.

    As for it not emitting a beam anymore, the MCA and/or crystals may have been damaged with the increased power. Did you notice a burning smell or did anything get hot when running (board could be damaged)? When you turned up the pot, did it go out immediately, or did it emit a green beam, then just stop?I'm sorry to hear that this happened - it sucks.

    It lit many times on 270mA. Maybe newly installed RCR2@3,6V has something to do with problem ? Sorry about very crap mobile photo.
    If the greenie will give red glow/ and Ir, what is problem then ?

    This happened to one of my greenies a long time ago. I didn't even turn up the pot. No more green, all that came out was an very slight red, only noticible when shone on a wall a cm or so away. From my experience, I'm pretty confident your diode is fried. One of the crystals most likely burnt out, thus preventing the IR from being turned into green. Don't try to send it to a specialist to get it looked at. It's too much time/effort compared to just buying a reputable unit from a dealer.

    The moral of this story is:
    Don't buy ebay lasers! They're cheap for a reason!

    Dont use RCR2 with the GLP - they dont give off a true 3.0V current and can/will damage or overload the circuits.

    Hi
    I did just managed open the whole Unit. It was very hard to open.
    I was using brutal force, but nothing was ruined mechanically.
    Pictures later.

    Here is all the parts






    And led light passes through optics

    Still nothing else, but red glow.

    Hm, it's possible the diode was damaged with the increased current. Another thing is the batteries you were using, were they CR123 primary cells or RCR123's? RCR123's wil kill the didoes in these lasers due to the initial voltage of nearly 4V.

    If the diode is damaged, it can still be showing up with proper current draw..however most of that energy is probably being wasted as heat. As for why you are seeing red, a damaged diode would explain this, it takes a certain amount of pump energy to meet lasing threshold in the ND:YVO4 crystal. If that requirement is not met, you will not have any green output, only the dull red near-IR.

    Sometimes rotating or moving the crystal around helps, try that and see if you get any green.
