Big fans of the lighter blue to cyan (473, 488 etc) range as it's less common but if I had to pick one colour a nice gold-yellow. 6W 577 is one of my favorites, it literally looks like painted gold light.. hard to describe. 573 is sort of pineapple yellow, bit greeny, extremely bright but only...

I've always said beam quality is king when all else is equal, for most uses in entertainment or pointer attributes. Because it means a higher power density over longer distance = moar pewpew. In same way, beam quality same or better and higher power = better diode array, or better as a solo...

Very cool thank you, jogged some memory cells. I'll be a happy man when that tech is commercially viable and may even try help in that regard! Knife edging is still the way to go for more simple diode combining, there are some other tricks but it's still year(s) to go for visible development.

They are what is used on the Miami hard rock cafe. 8x400W per beam, literally beam quality of a bunch of pointers stuck together without wavelength beam combining, so the power density is pretty low. Looks about ~1mrad region maybe more if you check beam width at termination versus emission...

There are small isolators and fibre in-line ones but a decent isolator typically costs more than a high end laser pointer or most single diodes..

If you are meaning what I think you are that's way out of my area sorry, but that subject has been more often approached outside of the optical realm historically for a number of reasons. But of course there are some interesting laser experiments when it comes to quantum aspects of reality! But...

Demand for that is driven by market, right now what's out there is 'enough' for most applications. Just like how red diodes have gone almost nowhere except some slight power increases for single mode. The tech is there for decent jumps in red but no one wants to pay for it outside of massive...

I can guarantee you will never see an official datasheet with that model designation. Why that is I'm not allowed to say sorry. And keep in mind I was the guy who was laughed off here years ago by some prominent members for saying 3W+ diodes were coming soon, when they were just breaking 1W.

I'm not sure if there is any criteria for this thread and since ya'll want some more red, have 12W of single mode array red :D Loving the HeNe porn thank you! P.s. found a manufacturer making new (reasonably affordable) HeNes recently, no yellow though sorry :x

Typically red diodes are at risk the most out of the standard diodes/lasers most of you will have (that said I almost only have experience with large, high power arrays of single mode reds in this manner). Blue diodes are pretty resilient to this as I have done some experiments to narrow...

Very restricted to each industry e.g. we can't go use it to make medical stuff, similar to how you get ball lenses to deal with.. But not R&D only, it's available just cost prohibitive for laser shows for normal projectors at lower volumes and OPSL is more viable and easier to integrate in lower...

Oh awesome! It's basically perfect then, I missed the USB recharging part on your website link.

It's exactly what is shown but not the entire design. Was asked for a link to it for sale of which there is none. The information posted is not available on their website either but it is public if you find it, I was given it by the manufacturer in this case (again, no link). I don't spend many...

Close enough. Nice work.

At around 20-30W RGB you can hear noise a laser makes on dark surfaces, it changes with the scan rate. It's very uncanny and ominous. Particularly with a lot of blue on corners of square patterns where the laser draws a few more points/dwells longer. My theory is some sort of dielectric...
