it was a rewritable drive so i assumed the power of it would be higher than the laser pointer

So if I leave out the PD pin, the laser diode would attempt to work on it's maximum power and burn itself?

I didnt look directly into the beam, I compare the brightness by aiming it onto the wall next to me, thanks for the concerning 😅😅 I don't have any resistor on hand, but I would definitely go buy some a few days later! Thank you!

i think it is 660nm. Current being too large would lower the "brightness" of the laser?

I have dismantled an old DVDRW drive and taken a 4-pin laser diode from it. After connecting it to two 2A batteries (red with positive, and blue with negative), the light beam is diverging, and the brightness is even dimmer than another laser diode that I got from a presentation pen. Also...
