OK what i did to check the current was just use the positive and negative leads and turned the laser on and used the leads to check the current. Without hooking up the diode. Then I hooked it up and tested it. Also the connection is soldered and wrapped around electrical tape As for the...

Ok first of all thanks to all of you for your great help :) MUCH appreciated! :D:D:D Now i just have 1 last question. Would it be fine if i use the same driver and just get a new diode? Since there is a very high chance i killed the current ones beforehand with the adjustable driver from SL...

Changed them still the same problem :/

Ok ill try getting new batteries in the following days and tell u the results. Hopefully it works :P

Yup 2 18360 batteries both in a series for a total output of around 8 V and yes they are fully charged.

Here are some pictures and if you guys want i can send you the video of the lasers behavior NOTE: I used another diode (the one with the black heatsink, 1.8W) to see if it was the diodes fault but they both behaved the same way. Also the Copper heatsink diode is the original 2W diode that i was...

I dont know tbh.. I'm guessing its because of the first driver i used which was a variable current one which was set to 1.9A but it shouldn't have killed it. When I hooked it up at first it flashed a bright light but then i disconnected it and for some reason when i turned it off and tried...

Ok so recently i have tried building a new 2W laser using the M140 diode from dtr's laser shop. Even though i killed 1 driver and had to order a replacement, it seems that mi diode may have died as well :( The only sad part about it is that i lost a lot of money prob over 70 USD without...

Ok so i was going through the SurvivalLaser website and found that they have a new type of driver (linked bellow). Its current adjustable and has an efficiency of ~90% my question is can i use it with the M140 diode and set it to 2A of current so its more powerful. Also would the power be...

Thanks a lot. Also i hope im not annoying you with anything or so but is there an equation as to how you calculate the output power of the diode? Andwill this laser go over 2W if i use the 1.8A driver?

So just to make sure i can use the 1.8A driver without a heatsink correct?

This is the driver i want to use for my M-type M140 diode(link bellow). my question is do i need a heatsink? since i know i gotr the 1.5A version and it may have overheated or possibly from physical damage. But thats beside the point. Does this driver need a heatsink?? Thanks a lot for any help...

Ok so i've started working on a new laser. Its a 445nm using the M-type m140 Module. However the problem is i dont know how many amps my driver should be and what is the maximum i can do without heatsinking the driver. I want to go for a 1.8 A driver as shown below however am not sure if it...

I know this is a bit out of context but from going down powerful lasers I've seen on youtube and in general I've never seen any 445nm that's over 6W from a single diode why is this so? is advancement going really slow or there's no demand for higher outputs? (Note: i know IR 40W lasers exists...
