my 445nm "super cold" laser module

[bweasel78]

thought id show you guys my very adequatly cooled 445nm laser, its a 1WATT 445nm ld module from odicforce laser (highly recomended website, AA++) A cpu copper core heatsink from an old desktop and three 12volt dc fans, plus a small alu heatsink on driver board. iv had it running for a couple of hours without it even getting to body temp.... its rather good also you may notice the red tube at aperture, its my focus adapter that i made.. not very pretty i know but very effective....

wow thats a lot of heatsinking:wave:

Re: my 445nm "super cool" laser module

Nice to see, and all of that you made it yourself is a great start.. :wave:
let me guess next upgrade would be watercooled? or tec? jk

Holy heatsinking batman! O_•
I bet your output will be pretty stable!
Nice pics!+1

Thanks iv got 2 pelltier plates actually, i was going to use them too, but thought id try without them first so i didnt use up all my fun in one go lol.

Re: my 445nm "super cool" laser module

You know you can upgrade that beast with a latest diode H1600 from dtr and crank it up to 2.2-2.3A , and we're looking 2.5W here!!

Re: my 445nm "super cool" laser module

2.5watts sounds goood i think ill play with this for a week or two then h1600 here i come then i think ill pop the original in a hand held maybe....... ooh what fun i have got to come! i new cooling was important for the diode, but it amazes me how better it is with the driver running this cold.. rather happy with it... How would i drive a h1600? could i paralell two of these 1.2amp ttl drivers? i really like these ones there easy to fine tune and cool...

Re: my 445nm "super cool" laser module

You can use a Flexmod P3 driver or just combine 2x Ben-Boost 1100mA's that'll give you about 2.2A , or a LM1084/1085 based driver there are a lotsa options.. Just make sure you follow the safety guidelines for yourself and same for others near you!

from odicforce laser (highly recomended website, AA++) QUOTE]

+1 for Odicforce,

I just purchased some parts from their web site, deliverd next day

Re: my 445nm "super cool" laser module

lol epic overkill :horse:

xD

Re: my 445nm "super cool" laser module

so iv got a good choice of driver boards then, thanks for the tips guys it much appreciated... all this has stemmed from me buying a 532nm laser illuminator for my rifle! Two years on iv got a house full of laser bits and bobs working and destroyed interests come and go with me but this one is staying (whether it likes it or not ..lol)

 

[bweasel78]

Re: my 445nm "super cool" laser module

overkill it certainly is! why do something by halves.. i wanted a well cooled laser and iv got a very well cooled laser.. Thankyou for your recognition

BTW, i think you should reaplace your title with this:
''My 445nm "super cold" laser module''

there you go jim, title changed to my "super cold" 445nm
