I was wondering if there's something I can buy that can place in front of my laser to make small geometric shapes? I'm thinking of wanting to produce a triangle shape at the size of 1 inch at 10 yards away.

Here's the situation. I a red laser/light combo unit. I want to replace the red LD with a IR LD. It is integrated together to a switch so I can't just replace the driver board with something else unless I custom a board. I was hoping to replace the red LD (<1mW output) with a IR LD with...

I have 2 questions. 1. I'm looking for a single rechargeable 6V battery that's suppose to replace 2 CR123. I was looking at DX for the battery.. but couldn't really tell what would work. 2. I know there's a competing company to DX.. can't seem to remember their name, but remember that some...

I have a few questions: Is there a graph for green lasers mW versus mA? I've never seen that graph.. I've been looking for the last hour for this one.. How can you tell if your greenie has a IR filter? I have a few 10mW & one 20mW green lasers which I don't know if it has a filter or not. I...

I pulled out some 10mW green laser modules from some weapon mounted lasers.  I notice that they solder the board directly to the laser pins.  I'm just curious if these laser diodes are similar to the diodes we pull from our DVD burners.. such as having one side for laser and the other side for...

Just wondering what have you burned with your 200+ mW portable lasers that made it all worth it? Wondering what can I burn besides black trash bags, matches, and dark gray foam.. I was thinking of bumping up my power of my laser to get better burning power.. cool to burn, but takes a while.

Last week I visited a few companies that used laser engraving machinery, as well as laser welders (used for Hermetically sealing) It engraved on different materials, and I guess on Titanium it's able to engrave in different colors.. pretty cool stuff. Any case that got me thinking.. What type...

I bought a few different gun mounted lasers and ripped them apart.  I noticed they use all used a different casing than what I'm use to seeing (Aixiz and Medirth).  Is there a place where I can buy these type of modules to house my lasers? Also I noticed that they have a really small circuit...

Just wondering if there's a way to tell if there's a IR Filter on a greenie. I have a few 10mW green lasers, but don't know if they have filter. I was told they did, but since it came from China, they would tell me anything. Thanks for your help.

I'm converting one of my lasers from a red laser to a ir laser. I want to make the IR laser be around the power of 10mW, but can't seem to find the graph/chart of the IR laser's mA vs mW output. I'm using the IR laser found in some of the LG housings with the high power red open can laser. I...

I just built up a KES-400A bluray laser, FlexDrive set to 30.4 mA (I changed out a 8k resistor for a 25k resistor to put the FlexDrive to 30mA-40mA current limit). (Based on a chart made by DrLava) I'm estimating my output power to be around 9 mW. How much risk is there for eye damage if I...

FInally powered a BluRay LD today with 63mA. All afternoon I was frustrated that I couldn't get a beam out.. I was using my calibrator on the LD, current limited to 30-40mA, and it looked like non focus light (guess what it was that), and I thought I had a LED.  I always thought the laser diode...

I was wondering if some of you unlucky people who damaged your LD, to become more like a LED, could post some of your pictures of it's output.  I wanted to see what it looks like. And what have you guys done anything with it after it's blown? Used it in another project?

I was wondering how do you determine if a KES-400A Diode is good? I recently ordered 3 PHR-803A KES-400A sleds from Daedal.  I harvest them from their sleds, and wanted to determine if they are good.  So I decided that the best way is to take my trusty Fluke 189 and measure the diodes.  Here are...

I was going to build up a IR laser since I have some NV equipment. I plan to make it 5mW or less.. Would I need eye protection still since it's low power? I would assume so since it's a non visibile spectrum and your eyes won't react to that light being shined in your eyes (assuming someone...

I'm buying my laser for the wow factor of burning things. Currently I don't have goggle but plan to buy some. Laser parts will come in before the group buy.. so if I setup and "play" with my laser (250-300 mW) shooting min 10 ft away without risk of reflection, will I be safe? Thanks

I was told to use 4 diode in series and a resistor. (Looking at rkcstr's test load, I see his load use 3 diodes and 1 resistor, and 1 resistor for discharge.) So that lead leads me to wonder which diode (not laser) to use, and should I use 3 or 4 diodes? Resistor I'll use a 1 Ohm to keep it...

I was wondering what's going to be the difference between using a 3 AAA versus using 2 CR123 batterys for a 240-300 mW laser build? I wouldn't think power would be effected since the circuit is regulated by a FlexDrive. Usage time probably would be less with the AAA, though don't know how much...
