You can get the neutral case 505nm laser (Sharp GH05035A2G) from Dongguan blue universe (Chinese company on Alibaba). It's just $6 each.

may be their eyes are already blind 😂.

I though you need to use my $5 thermal paste xD

That's very powerful in the very small host!

I though this model might be the laser version. However, I can perform the wavelength measuring using the blank CD-rom as Diffraction grating.

decan is the best method I though. but I will be risk because the dusk can get touch the laser diode chip. I've done some window cracking and 1 of laser survived (My 515nm T-DRAGON build).

Hello everyone. I just got my 2nd laser diode from bu-laser company. this is the 505nm laser diode. I tested and it has the neutral case. So I can confirm that laser is GH05035A2G. I compare the host of the fat beam laser with my 505nm inside. I actually use the host and driver of 405nm fat...

UPDATE. The 2nd laser arrived. Tested. It's neutral case 505nm laser

It will very useful to add another protection layer to the laser goggles.

or his friend mean 405nm ? I saw mostly on ebay advertised as "UV Purple laser".

Thanks for guiding me.

I really want to try with my Sharp 515nm. Unfortunately I can't find the source for LN2.

I known that if laser diode cool down below the 0 degree celsius will shift down the wavelenght. Styropyro and Brainiac had done something like this. Styropyro dip the red laser into the container filled with LN2. Brainiac put the cheap laser pen pointer (405,532 and 650)in fridge (4 degree...

hard work on laser and works ! cool laser. I though you need the thermal paste for head dissipating from the laser.

Why Using laser pointer ? Laser pointer is for pointing. The name is telling you. Or you mean laser to etch the PCB like CO2 laser ?

Cool green ! Frist time I though why the beam is so thicc. You are using the beam expander.

Yeah, You right.

I use my T-DRAGON 515nm build to shepherd the chickens.I use the original parts from the laserland 510nm laser pointer.You can buy this for $17 .It takes 2 of AAA 1.5 volt. You can use this I guess.It's much safer than the 532nm laser pointer. Also more stable.

Cool laser !

Sawadee krub.I'm also from Thailand. Happy to see another Thai people on LPF 😀
