1W blue laser brightness problem

Hi all
I recently have made a 1W blue laser in a c6 cree build with a m140 module from DTR. I got the one which incidentally does not say 1W in the website. Now I'm wondering whether my laser is really that bright as a real 1W blue laser because I have seen other sites on LPF saying it is about as bright as a 100 mW green laser which can be seen in daylight. Mine can't. Please advise, especially if you are DTR.:thanks: I also have a 1.25 A driver. Is that the problem? :thanks::thanks:

it burns like :eg:

What you need is to test the power with an LPM to see if it's performing as intended.

you cant tell power by eye
make friends with a member who owns a LPM- one that also lives in the 'milky way'

this looks mostly like a post building thread- DTR 9 if you dont KOW how to search) is the person who wouild tell you the M-140 doide is capable off more than 1000mW BUT high power equates to shorter lifespan- so yours may be set low for that reason- 1.25A will make a 445nm M-140 diode put out close to 1250mW very effecient diodes and robust too-- & its true 100mW of 532 is equally bright to our eyes as 1W of 445*

*WHEN looking at the dot NOT the beam--

sigh

Thanks guys. (Especially hak) Ease of heart now.

If you're still not sure that your 445nm is performing up to spec., you can probably find a member here that will LPM it for you at no cost.
There may even be a member or two that lives in your part of the Milky Way!

That's the way to place it Bowtie Guy!
And if you check out my location, it's something more normal now.
@hakzaw1: Just did the not-funny Milky Way kick because well, I don't want to just tell everyone about where I am and let everyone know my exact age! Sum it up: Privacy.
To all you Galactic Hitchhikers: I am in Galactic Sector ZZ9 Plural Z Alpha! :wave:

You don't need to list your age for us to be able to tell what it is. Sometimes kids just kind of, you know - act like kids. While we all like to see people being enthusiastic about this hobby, I'm afraid you are going to have to tone it down just a bit if you want to make any friends here. Lurk more to learn what you want to without making yourself look bad.

Yep. Thanks, Krowbar. Gotcha. +Rep:thanks:
