... I've ordered an 30Watt-MOPA-M7 fiberlaser with variable pulse-length in exchange for my actual 30Watt with "fixed" pulselength -- while the actual can only generate pulses with 200ns (wwats too long for my actual project), the MOPA-M7 can vary between 2ns-350ns. Here the box, that came...

Thank you to everyone who has replied. I really appreciate it. I found an OC at Laser Components (laser-components.com). Here are the specs: PR500-1000/50/AR PW0512UV Output coupler, side 1 R=50% +/- 3% @500-1000 nm, side 2 R<1% avg. 500-1000 nm 12.7 mm diameter, 3.2 mm thickness, fused...

Are they still available?

With that IP address and subnet mask, you can set your computer to any IP address between (including) 192.168.1.2 and 192.168.1.254, except 192.168.1.234. Your computer will need the same subnet mask of 255.255.255.0. I seem to recall seeing some weirdness with modulaser and network settings, but...

You are right of course. I have some vaseline glass, but some is just uranium glass. Its often used interchangeably

Hmmm... I've always heard it referred to a "Uranium glass", since it's a uranium oxide that gives it the yellow-greeninsh (Vaseline) color. Wikipedia has a nice short article on it: https://en.wikipedia.org/wiki/Uranium_glass Ron

I have a few big pieces including a large cake stand and a Lalique (which is my avatar on LPF) but most of it is early 20th century jewelry I bought for my wife. So it was fun for both of us to see your stuff in the video. Keep collecting :)

Touchdesigner is good to go. Except jitter when it comes to signal processing. Hmmm.

i have no experience with modlaser, but if sitter can see it, everything should be good to go.

Correction: I downloaded the file again - now i got full access. But modulaser refuses to find dac. any idea of why that might happen??

Hello. Thx for replying. I erased the txt. file. Then i got access. Could not make modulaser find the dac. After that an error occurred errno 10051 a socket operation was attempted to an unreachable network I then realized i had not set my computer to auto-assign. But now i am back to...

Thanks, the glass collection continues to grow, i just love it.

That place was cool! Glad we are back again.

Beautiful vaseline glass everywhere.

Very cool and hope you get it done and post when you are finished.

My only submissions

I really like the second image, much like the original but with the new lettering. The new font looks great! Greg

Howdy folks, I’m submitting a couple more for your consideration. Laserjock, sent over a style font that I’ve incorporated into the logo. Also adding a couple with a slightly different phase angle but with the same 1x, 5x ratio.

Damage to the LEDs themselves shouldn't cause LEDs to stay ON. That sounds more like a problem with the driving circuitry. I'm not super clear on how the whole tiles are put together from your description, but I would certainly look at the driver circuitry first, assuming it's separate from the...

Looks like 75$ per module. I'm looking at it, but graphical programming languages usually die a quick death. Labview is always too slow and too tedious for me, but I have to use it. Steve

Yea that is what I was thinking. I have an unfinished CNC router in the garage that is made from really thick Bosch Rexroth T-Slot. I never finished it, but it has NSK ball slides and I have a Gecko 4 axis driver, K2 CNC 5" Z axis for Bosch router and right at start of covid I had custom 10mm ball...

Usually if the rod is uncoated, it is a weakly convex or concave HR, and a long radius OC. Ruby systems tend to be designed for a highly optimized cavity to deal with immense thermal lensing. Sometimes their designers like negative numbers, thus will use a slightly convex HR. That is also...

Yes, I still enjoy good beam work... more commonly used as stage lighting, to accent and augment a main act. Laser art is as versatile as music. Different strokes for different strokes (and intent). Beam work? Good fog. Projected imagery? Bad fog. Exactly, no brainer click on every beat. Look at...

Steve, what is the typical mirror configuration for a ruby laser with external mirrors? Do they use a planar OC and a concave HR? Dual-concave? Or are both the HR and OC just flat, planar mirrors like you'd have when the mirrors are bonded to the rod ends? Adam

Wonder if you could build an x/y table to automate the LED replacement process? Thinking of something that operates like a commercial pick-and-place robot for PCB manufacturing.?. If you have to place everything by hand, you'll need a very steady hand. Could you use a heat gun to loosen the...

I agree that it's difficult for laser graphics shows to compete with film, to say nothing of Virtual Reality. These days you need to pick your audience. Some people still "get" lasers, and those are the ones we need to cater to, at least for any sort of show were the main focus is an image that...
