So I've built a couple of lasers now. Ive got about 10 of 1.8a using the m140 445 diodes. Also have a 2.2a powered laser using the 9mm 445 diodes.
My main question is how exactly do you measure all the measurements on a laser.
My laser is powered by a 1.8a driver. Uses two 3.7v batteries giving it a total of 7.4v. Now in order to get the Watts of the circuit you would multiple VxA which would be 13.32w.
Maybe im getting it mixed up. Do i have to use the mA off the battery to get the correct calculations?
so if it was a 1200mA 3.7v battery, That would give me 8.88W.
Does that sound about right?
But when I go back to the information when I bought the diode, it says it is a 1.8W 445nw diode. So what is the 1.8w mean exactly? What the output is? What the diode can handle?
Just trying to understand what the information on these diodes mean exactly and how to predict what they can actually handle and what not.
Thanks
