Hey all, I have a decoder board that accepts both ILDA and Bluetooth input. The board does very well controlling the colours of an RGB laser source. My issue, though, is the board only has an [Y,N,X] output for galvo control. All of my galvo drivers (this is just 1 example, I have 15kpps...

This is a rare 975nm IR pump diode. I don't want to destroy it. The Vf is 2.5v (max) the If is 700ma (max) I'd love to drive it around ~500ma. I'm thinking of limiting a stable meanwell 5v source to 2.5v using an adjustable voltage regulator, set physically to 2.5v I'd like to take that 2.5v...

I've been searching for 589nm laser light for the last decade. Luckily circa 2023, we have low power nonlinear optics which can produce similar light... But, prior to that... The best success I ever had at getting something near 589nm (sodium emission line) was to pump a Rhodamine 6G +...

Hey guys, long time no post. I've got a Coherent branded FAP 808nm +/-3mw source, rated for 40w of optical output. Based on the datasheet it has a Vf of <2.2v for the array. Its threshold lasing current is ~9a, (mine begins to lase around 8a, but my bench supply fails after 10a, so I can't...

I think the title is pretty explanatory. Background: I'm designing my own ESP8266 based PWM 3 channel driver. I'm using a 0-1500ma CC driver (LD06AJSA) that accepts a wide-band PWM input. I'll be using the ESPs PWM output pins for duty input to the CC board. Question: Let's say I'm giving the...

I know this is a bit off topic for the typical use of LPMs, But I need to set up a variable intensity UVA-UVC source, using multiple LED diodes at discrete wavelengths, from ~400nm to ~280nm. I do realize 280nm is the high-end of UVC, but the source in question doesn't need to go lower...

Well, I don't see a 589nm beam in my near future, mainly because it's unlawful to import - and Frankly, I just don't want to deal with that right now. I was considering metal-printing a mount to create a simple red+green combining module, throwing a dichro in, and calling it a day. Can still...

So, I've never actually imported a fully built pointer into Ontario, Canada before. I'm not even certain it's legal to do so, and I'm looking for advice in this area. I've always purchased the parts, hosts, and bar stock and milled the pointer myself, done some testing, and later disassembled...

So, I really wanted to get into some of the more interesting Blue wavelengths, and I decided that 488nm would be a perfect introduction to the 470nm<x<490nm wavelength range, well, without breaking the bank. I don't have many build pics of the entire laser, as the build was rather...

Hello everyone, I'm working on a very simple, very cheap host to accept either an Aixiz module case or green assembly. As I'm a new member here, I figured I'd post the entire thing as a quick tutorial, as it truly cost me around 10$ in hardware store copper, a few dollars in tools and around 2...

So, I've done a lot of resarch about this, and I'm wondering if anyone has any first-hand recomendations. I'm putting together a mini 638nm pointer, hoping to get around 500mw from it (nothing too crazy, for battery charge lifetime) but I'll be powering it with a single 3.7v protected li-ion...
