I like that idea too! Hardest challenge I faced was isolating of the HV output of the power supply from other components in the box, you can read about it above but initially had the HV line a little too close to a mounting screw and didn't realize it until I flipped the switch for the first...

I built everything into one of those harbor freight "pelican" gun cases, plan on adding a shoulder strap to it once I finish building the handheld portion of it

Yeah got the proper goggles. I purchased a focusing lense but haven't mounted it on the end yet, but it burns just about everything I tried with just the raw output of the tube, instantly catches cardboard and plastic on fire, creates a small molten spot on bricks and rock, it's wicked for sure

I liked the idea cause it's crazy and you don't see to many of them, practical? Not really but I've only seen it done a handful of times. Drains that 9Ah motorcycle battery in probably 5 minutes

That's awesome, I don't think I ever saw a co2 tube that small. Haven't posted in a while, but it works! And it's a beast, I think I need a bigger inverter, can't seem to get it to full power, or maybe it's too much voltage drop on the battery? Will need to do some tests. I can get it up to...

Yes, definitely one of my more crazy ideas that's for sure. That flash over incident I mentioned in the original post was exactly that, I completely overlooked the location of the high voltage lead from the power supply being so close to the mounting screw of the terminal strip, i will be...

Here's the latest project I have been working on, haven't seen it done very often, a handheld Co2 laser, purchased a 50watt tube, and been working on putting together the control box for it, using a 12v motorcycle battery and a 500watt inverter to power the electronics and laser power supply...

Unsure if correct forum, I didn't find any of the 1064nm variety. After originally considering a ruby laser, I ended up purchasing a JK-700 ND:YAG cavity assembly on eBay, and will be doing some experimentation with is unit, manufacturing quality. From my research it seems to be designed for 350...

I read through Sam's laser FAQ, lots of good info there. From my understanding the HR mirror needs to be as reflective as possible, and the OC mirror needs to be 70 - 90% reflective at operating wavelength, 694nm in the case of ruby. I also remember reading somewhere that optical cavity length...

I will check them out, definitely have time, flash tube is shipping from the ukraine and the ruby rod is shipping from russia so that will probably at least take a month, need to start designing a cavity and then still need to solve the mirror and lense issues, everything is mostly taken care of...

Been a while since I have been around here, took a break from lasing for a while, but recently started working on designing and building a hopefully functional flash pumped ruby laser, been experimenting with some large flash lamps, at relatively lower energy levels with regards to a powerful...

Thanks! and it took me about 10 mins to assemble and cost was probably about $60 - $70, purchased laser diode and modules from ebay, and driver, heatsink, batteries, and host from survivallaserusa, also built a 2.5 watt since this post, that thing is wicked!

I have read about the photochemical damaged caused by the blue light, what are the symptoms of it? and i use safety glasses 98% of the time when using a laser indoor, and when i am not wearing the glasses i never view the dot or beam for more than a couple seconds

I am glad i asked, and i will always be skeptical to buy stuff like this from china, finding a propper pair of glasses now, thank you

I know that dot viewing of a 2 watt laser is not necessarily the safest but i am sure that everyone has done it at some point in time, i never look at the dot at close range (<10 feet), i always make sure it is on a flat black surface, and never do it for more then a second or too, hopefully...

Currently i have ebay glasses from china until i get the money to buy a quality pair, i got two pair for about $20 green lenses, here they are 2pcs 405nm 445nm 450nm Blue 808nm 980nm IR Laser Protection Glasses Goggles OD4 | eBay OD rating is 4+ and the T rating at the 445nm wavelength is 15%

I do not have a laser power meter to test them but I did a simple test of shining the laser through them and the dot is reduced to almost nothing, I know that isn't the best test but it does show that they are blocking the majority of the light

I purchased a pair of 445nm laser glasses with an OD of 4+ and while wearing them and putting my 1 and 2 watt 445nm lasers next to each other on the wall, the one watt appears white and the two watt still shows as blue, I assume this means less is being blocked, but just how much makes it...

I only had the problem with one switch and confirmed it was indeed the switch by trying the bad switch on a different host, the company is sending a replacement. It should not have failed within the first few minutes I had it, just wanted to post this as an example of laser safety, always make...

i have tested the cap on both of my c6 hosts and it will not turn off, it was working fine when i first got it, may try to disassemble and see if i can fix it, when i recieved it the box did appear kinda crushed, something may have gotten knocked loose in shipping
