Alright, I'm making a custom burning laser lighter, something I'm sure others have done, and I have a few questions.
Battery size is a major concern for me, and since I'm using a high powered infrared laser (1W, 808nm) it takes a lot of juice.
I've obtained a driver that can limit the current from 80mA-500mA.
I've got a little electronics background, but hardly any with lasers, so here's my question:
Will using higher voltage vs lower current have the same result as higher current and lower voltage?
I know I'm making a huge assumption, but here's my thought process:
P=VI right? So if the goal is a 1 watt laser, then I should be getting 1 watt either way. For example, 1 volt with 1 Amp would be 1 watt. So would 2 volts with 500mA. So would 4 volts with 250mA.
I would guess that using less current would probably be safer for the laser, but I don't know if I'll be sacrificing performance for it.
Will these changes with my power supply and driver affect the overall performance of my laser? I thought I remembered seeing something about current threshold for specific lasers, so I think I must have something wrong.
If someone can explain what I'm missing, that would be great. Thanks in advance.
