Improving a laser beam spot for a diode (solid-state) 445 nm powerful lasers

Endurance lasers is working on an improvement on a laser beam spot for laser diode NICHIA 445 nm.

Thank you for this video. I learned a lot from you.

you are welcome - here is a end result endurancelasers.com/some-experiments-with-laser-beam/

hey guy, I have bought 3 corrective lenses for my laser pointer for fun, and later I wana install them into a laser pointer build. Im wondering how you have set up your lenses inside that device you built. Their spacing too and stuff. I see youve put them before culmination lens which I will try to take advantage of

easier to see on black velvet. geat presentation, thank you!

[@denniskramer9788]

Did I ever try a plano convex lense...shoulder best and inexpensive

[@rs-bk2567]

Подскажите, поставил в 15ватт китайский модуль у которого фиксированный фокус 18мм, диод nubm44 v2 , вместо точки такая же полоса как у вас на видео 6:00, и когда дал на всю мощь диоду, линза в центре прогарела, как будто откололся кусок стекла. Можете что то подсказать?

Can you please make the video, how to focus stack laser beam for tiny spot...!!!!!

Можно использовать головку от гравера К40 с цилиндрическим профилем зеркала и 12 мм линзой на 450nm

[@Endurancerobotschannel]

думаю да

[@adypenney]

Will this be out. For sale and testing

[@Endurancerobotschannel]

yes, soon enough

[@mr.wiggles9827]

Is it mirrored surfaces directing the beam into a square shape....or are you just rotating bolt heads together essentially absorbing all that usable energy in the brass or whatever that's made out of.....

[@gdempsey17]

Hi. Did you ever put this up for sale?

[@martinedwards6387]

What is the point of having a circular dot at 2.79 metres? I have never lasered anything at 2.79 metres!! Surely you need a circular dot at around 30 mm?

[@randduhe1526]

Its a matter of illustrating beam quality. If the laser is collimated to a more or less circular spot when projected at a few meters, then it is most certainly circular at the short distances used in laser engraving and etching.

[@animadoarts5123]

279m ???????????????

[@Endurancerobotschannel]

pardon?

[@bnaivar]

I just put a washer between the diode and the lens.

[@watahyahknow]

that works but i think that allso reduces the power , the
bit of square glass actually bends and concentrates the light from a regtangle intoo a square
