I have always loved lasers. Since my dad gave me a little 5mW red laser as a child, to buying green lasers from China over the past few years. I am almost ashamed to post this up here seeing some of the beautiful lasers you guys have put together on here. I decided to try putting one together...

Would it be okay to test a S06J at 430mA in a heatsink without thermal compound? The laser wouldn't be on for more than 30 seconds. The heatsink is a 1 inch diameter aluminum disk with a 11.9mm hole drilled in it for the module. The module is a Aixiz with a copper diode mount.

I was wondering what diodes I should look at as an introduction to the "other" laser colors (not 405,445,532, etc.). I was looking at some of the offerings and they are very expensive. A yellow laser started at like $600, cyan lasers were more reasonable. Are there other wavelengths I should...

I am looking at doing a 12X build. The only issue is I am not sure if I will be able to build my own driver that will work. Would it be possible to build a 480mA driver with an LM317 if I use a combination of 2x8.2, 47, 9.1 and 100[ohm] parallel resistors as the resistance to set the LM317? I...

How does a dummy load represent a laser diode? To my knowledge all I need to make a dummy load is a bunch of rectifier diodes in series with a 1 ohm resister. What does this do to simulate a laser?

I remember reading about a Aixiz brick and mortar store in Houston. I can't find the post anywhere though, and I've tried googling for it to no avail. Does anyone have any information on it or did it never exist?

I ordered some 3.8mm Aixiz Blanks for a 805t. It seems that the module is too small for the diode to be pressed in. I have never built a Blu ray before though. I will link pictures to how far I can get the diode in the module with out applying too much force. http://i.imgur.com/xAHLE0S.jpg Here...

I read the sticky about soldering diodes, but I'm still worried about it. I have one of these kits. Talas - Extra Hand Clamps Can I use that as a soldering heatsink? What temperature will fry the diode? I have a soldering iron that lets me set a temperature, up to 300*c.

The capacitors I bought for my driver are .1uf and 1uf, both with a 50VDC. Is this too much? Also, I hope the resistors I bought will work, they are 1/4 watt, and 5% I am building a LM317 driver, with 3 capacitors and a 1k resistor in parallel. There is also one 12 ohm resistor in series after...

Does anybody here have any experience with Dragon Laser's safety goggles? I already have a good set for 532, I am just looking for a set for 650nm (300mW) and 405nm (50mW, will be building a PHR and maybe a 6x down the road). I am not working with any class IV's, I just want to be protected...

Where should I place the capacitor when following this diagram? How many farads should it be? Thanks a lot.

I recently recived my 300mW "cute host" red laser and the 200mW green in the same host. The red laser seems to have a MUCH wider range of focus than it's green counterpart. When viewed with goggles, the green laser dot gets to be maybe 2 cm diameter at its widest, where the red can be inches in...

I do not have a brand name for them as I bought them two years back. But they do say 532nm on the inside of the rim. In addition, when I shine my 5mW DX greenie into the lens (WITHOUT IT ON MY FACE of course ;)) nothing comes thorough. I am asking because I want to be protected from the diffuse...

I recently bought a "5mW" green laser that is pretty overspec. The only problem is, it takes a while to warm up (I thought it was broken at first). However, even when it is warmed up, it'll be very bright (30mW) for maybe half a second then drop down to probably 15mW. The violet laser i bought...

I was messing around with my 20mw green laser and I decided to shine it into a blue gem (not to sure what kind). Yea, a dumb idea... but anyway, the gem turned into a red color when the laser was shining into it. I immediately stopped cause I thought that was me getting a dose of pure IR. Was...

I got a 5mW laser for cheap from LedShoppe. It's a great product for the money. I was just wondering what this artifact is on the side of the laser dot. It's hard to see in the photos but its very evident IRL. Is it something that can be fixed or is it something with the diode itself?

I got my 5mW from Led Shoppe. It was listed at $12.99 but I got it for a lower price :p. In all it took about 8 days to ship which, although its a long time isn't as bad as what i've heard people face with dx and those types of places. Led-Shoppe has great customer service. I've heard of them...

Do you guys think that using posi-locks on the diode instead of solder for a first time build would cut the possibility of heating up the diode? Or would it not even work?

Okay, so I have two questions. On the LM317, how do I know which prong is VIN , VOUT, ADJ? And to figure out how much resistance I need, would I use the formula... R= 1.2/Iout? So if I want 150 Ma I would use a 8 ohm resistor?

Hello, I've had a 5mw green laser pointer from dx for a few months now. But seldomly used it. I changed out the batteries and it ran good for a while, then wouldn't shine anymore. So I changed the batteries again, but no dice. I opened the case and saw some shoddy soldering but, what can you...
