Hello again, friends. I've been absolutely swamped with work lately, so I haven't had any time at all to post any builds. Here's one that a guy requested recently. It's an NUGM01T in a Kryton Groove I got from BudgetBeams.com. I went with a 2.4A X-Drive from DTR. I will upload power results...

Hello friends. So I've run into an issue with a BlitzBuck driver. I'm running it at 2.4A to drive an NDB7875, and it appears to be going into thermal protection mode. After about 20 seconds, it starts blinking very rapidly, with increasing speed. I ran it without a heatsink at first, but used...

Hello again my friends. I had several Ehgemus hosts laying around, and someone contacted me requesting an NDG7475 build, so I decided to build it into one of them. This host is one that I snatched up as soon as he posted because I just knew the acrylic focus adapter would look sweet. I refused...

Well friends, this is, I believe, the first handheld NUGM01T build on LPF. I know a lot of people were curious about this diode because it came out at $95 less than the NDG7475, yet appeared likely to have similar power capabilities. I actually bought this diode for myself, but a friend ended up...

So I was playing around with my lasers late at night, and I discovered an interesting effect when shining my lasers into the kiddie pool at my apartments. What's interesting is that it only happens in the kiddie pool, which is 1 or 1.5 ft deep. If I shine it in the normal pool, which goes down...

Greetings, my fellow LPF-lings! Today, I share with you my latest build. An NUBM07E in an MX900 host. I know I've been using MX900s a lot lately, but I do love the host and Rick's full copper modules for it. I've got one of Moh's aluminum heatsinks as well, so I'll be building one of those soon...

Hello LPF. As the title states, I'm looking for a beam expander. Something reasonable in price like the JetLasers 10x. They are out of stock, and I haven't yet found any others I want that are currently available. If you have something, let me know. I'll buy, and I also have a ton of hosts...

Hello again my friends! Just wanted to share my newest build with everyone. I actually had a friend who has built some lasers himself ask me to build this one for him. I went with an MX900 host and Rick Trent's full copper module and heatsink to give decent runtime. I used an SXD driver at 4.5...

Hello again my friends. Just wanted to share another build and review Rick Trent's nice copper modules/heatsinks. I really like the modules because the back half butts up to the back of the diode case. This makes for great heat dissipation, and it also allows me to actually leave the module...

Edit: Just for future reference, as I keep getting questions about the module not being flush with the heatsink, even after I posted the results of my testing on multiple threads. When using modules with a full copper back half, it does NOT make enough of a difference to sacrifice the ease of...

So, to make a long story short, I built a nice green 520nm build for this guy. It's a PLP520-B1 with a nice big copper module and heatsink running one 18650 to an X-Boost. It hit just under 250mW. I will post pics in the morning(it's 2am here), and I may end up putting it up for sale here, so if...

Edit: SOLD. So my coworker and I both bought 3+ watt 445nm lasers from Rick Trent about 2 months ago. Rick measured them on his LPM @ a little over 3.5 watts with a G2 lens. My coworker decided he wanted something less powerful and green, so he purchased a ~175mW green laser from Rick. He said...

So I've always been one to want to do everything as precisely and as scientifically correct(if that makes sense) as possible. Therefore, I have been less than satisfied with the "if it starts to get warm, turn it off" method of determining duty cycles. Upon searching, I haven't been able to find...

So I just received my Laserbee 3.7W USB, and I was so incredibly excited to finally get to measure my lasers with my own LPM, rather than driving across the US or shipping them off. Well, 2 hours in, I am incredibly frustrated. Upon installing the correct driver to my Windows 7 64-bit machine, I...

Anyone here have any experience with an Ophir DG-HH? I can get one right around my budget, but I can't find any info on calibration for this particular model. Anyone know what I would have to do? Send it to Ophir? If so, how much do they usually charge for calibration?

Hello, my name is Taylor, and I am quite new(3ish months) to the DIY laser world. I am in automotive quality, and part of my responsibilities include quality of seat rails welded by 4kW Trumpf lasers. It's fascinating to watch an invisible beam fuse metal, but it's not actually what got me into...
