ok. i still need the compact size... or do i... i could run the driver module outside of the heatsink body... i did find some TTL drivers on some chinese website for a little over 3.00 a piece... i just figured DTR's would be WAY better quality than those... but we'll see what he says when he...

hazzah! this is exactly the laser diode/driver combination i was looking at. DTR's 10mW 515nm with driver and body/glass lenses. maybe ill see if he can hook a few up to his power supply and see if they dim at the same rate... doesnt seem like a very complicated thing, but lasers are unlike...

nice, i wonder if DTR's are capable of that... because its definitely a bonus feature :) thank you i will definitely be having a look into this. well... more than a look... if im going to continue working with lasers, i am going to have to have at the very least, a basic knowledge of safety...

yea, well, i had no idea about the legalities of lasers... i honestly thought they were 'fun toys' first, and 'tools' second. boy was i wrong... but now that i have seen the error of my ways, im doing something about it. haha, ive had this username for the past thousand years... well, 11...

No kidding! I am close to finishing the prototype too... So i guess my next question is What is a good laser meter to get?

yea, ive let him know that i require a lasermeter if i am to finish this project. so, my understanding of this, is that if the lasers are all under 4mW, then i am safe. i have so much going on right now, and now, with the legalities of this, im kinda freaking out...

yes, i saw that, thank you for the information! i let him know that if i am to go ANY further with this project, i need a laser meter to detune to lasers down to 4mW or less. im sure these 532 DPSS lasers are over 5mW, they emit a slightly visible beam, even in daylight. if i am understanding...

Uh oh... ill bring this to his attention... i had no idea... thank you for letting me know! The last thing i want to do is get myself, or anyone else in trouble... damnit.

Yea! I found his site early this morning (1am) after watching StyroPyro's youtube video on his high powered 520nm laser. Already emailed DTR about the project. Just gotta wait till he's back from vacation haha. If all goes well, we'll need 200-250 lasers haha! Massive project. Just gotta hammer...

Ill definitely check out those links. I found DTR's site early this morning (1am) while researching lasers. Ive been watching StyroPyro on youtube for a couple weeks, and found one of his 520nm laser videos. He mentioned he got the diode from a DTR on here, and posted a link to his website. I...

anything online that i have compared these drivers to is different... all the LD drivers ive seen have pots on them to fine tune, these do not. this could be mostly where my confusion is coming from haha! yes, i definitely saw crystals. tiny little things, side by side directly in the path...

:beer: cheers! that is fantastic. ive looked up TTL diode drivers, and found some really cheap! now i just need to source the correct diode type, and i think ill be on my way to completing this project! i just looked up DPSS to learn more about it, and when i was taking apart the lasers...

i had no idea you posted that, as i dont get notifications for edits... this is why i double/triple post... BUT ANYWAYS, i agree with you here. i contacted my client, and we are looking into different types of lasers. I now have to do research on Direct Diode Lasers... where to get them, how...

THANK YOU!!!! This ^^^ is the information i was looking for... so these unknown lasers that i have are not going to work. i will look into the Direct Diode lasers, and PWM drivers. I finally have a direction to go! Thank you!

Oh, ok. Noted.

i built a PWM do dim the lasers. indivually, they all dim great, from a very dim dot on the wall, up to full power, and very smooth transition between. my problem is when i add more than 1 laser to the PWM circuit... one always dims before the other, and i do not understand why... if i connect...

i updated my thread. thank you for this information, maybe i have bitten off more than i can chew with this project...

done and done. and i was stalking for information regarding what i was doing, checking out a few threads where guys had built their own driver modules, etc. never got THAT in depth. sorry. this is exactly why i am asking for help :) correct. there were no identifying marks or labels on the...

Hey everyone, im new here. I live in western Canada, and do fabrication, including welding, vehicle modifications, gadget building, etc. i am 31 years old, and have been a DIY'er for as long as i can remember, always modifying this or that, taking stuff apart to find out how it works. I have...

Hello everyone, been stalking this forum for a while now for information, and have come across something that I cannot find any info about... I am building a 10 laser assembly for use on set. The requirements are: 10 green 5mW lasers 10 flexible arms allowing for independent positioning of each...
