Biden has been a dismal failure and a national embarrassment, I fear we will see WWIII if the deep State dems somehow steal another election and yes 2020 was stolen, covid was exploited to stuff ballot boxes and illegally change State voting laws, information that did not favor Biden was...

Closer to WWIII everyday. https://www.reuters.com/world/middle-east/iran-embassy-strike-shows-israels-growing-reach-mideast-boils-2024-04-04/

((( WHITE COURTSEY PHONE ))) Calling GSS to the fightclub. Has anyone seen GSS today ? I can't message him as his header has no " start conversation " tab.

I can't get out of the walmart/grocery these days for under 100.00 and I'm not even buying anything fancy.

Anyone used one of these or other similar ? http://www.lasence.com/Product/12033.html

Anyone else buy yourself a Christmas present while shopping online for friends & family ? I came across this little beauty and couldn't resist, got a sweet deal as well, $700+ from ThorLabs but I scored this one for but a fraction of that, it appears to be in excellent condition. Did anyone...

Has anyone used any of the Chinese/ebay PBS cubes or found any highly affordable cubes that can hold up to 2 x 9W laser diodes ?

https://www.ebay.com/itm/314841104261?var=613356490805 I just received my 1st re-canned NUBM0F and WOW ! Shipping time for me was 10 days including the weekend, so only 8 business days, not bad. I knew it was going to be good when it topped 6W @ 3A It just cracked 8W @ 4.5A and hit 8.6W @ 5A...

It's amazing that we can lithographically print/make these phase shifters smaller than the wavelength of light with equally small spacing...... what are they using to expose them, gama rays ? Well X-ray lithography will work for down to UV, until chip based X-ray...

This ad says these are 1W and are a different part number than the 500-700mw Sharp 520's Has anyone tested one yet ? I don't know how hard these can be driven, but I expect this is curtains for the old ndg7475 when these sell new for 40 bucks...

The last test of a " 30W " is curious, is it one of the mini 4 chip arrays, maybe a 6 chip, or could it be some new single emitter ?

NUBM0G is a new 465-470nm possibly good for 8W I have asked a Chinese seller about getting some re-canned with a window can and inert backfill. https://www.aliexpress.us/item/3256805772234397.html

Has anyone tested this laser diode ? They are rated @ 1100mw but the other Sharp MM 5.6 package 405nm offerings rated @ 350mw will do dam near 2W overdriven, I have several that have held up well @ 1.75W, anyway I'm just curious if these new diodes are worth the extra money...

I expect uv-c safety glasses should be worn when using this diode in a disinfecting flashlight, or is this even reasonably possible ...

A new RGB array, yes this price is ridiculous but the evolution is interesting, looks like they won't need to pump phosphor anymore. https://lasertree.com/products/nichia-465-525-639-643-647nm-65-5w-numm34t-rgb-laser-modules

Why is this advertisement on LPF ???? Do we now advocate pointing lasers into peoples eyes ?
