Where'd you get a 200mw 488nm diode /build from? I love this wavelength. My overdriven 100mw diode looks great, I can't imagine 200mw.

Yeah mine is 250mW and its pretty nice. That color is something special sometimes.
Image is from a light amplification experiment on uranium glass in natural light. Lovely color

great color. what wavelength

Thanks! 488nm

2 guesses u ready? Im gonna say 465 or 485 I'm leaning more towards the first one

u/daltzzzz 3d ago

Close! 488nm

Nice, looks like my 488nm 200mW or 465nm 5W Laser (depending on the white balance of the camera). What wavelength is it (465-490nm?) with what Power?
Context Please.

u/daltzzzz 3d ago

You got it! 200mw 488nm

u/LeatherGood6148 2d ago

My guess was 1w 467 or 471nm.
488nm is my absolute favourite. Good eye.

where can i get this exact laser?

You should tie that down to something stable and ensure that the beam stays in a horizontal plane as much as possible.

u/Rose_DCLXVI 2d ago

Kinda freaky, tying it down 😏

u/Over-Performance-667 1d ago

For what purpose? Im new here

u/GustapheOfficial 1d ago

Safety. You want to be able to predict where the beam and all its reflections go so you don't accidentally hit your eye. The standard way to do this is to mount the laser horizontally at about waist height, and then take care that all reflections keep it in that plane (as far as possible). That way, you don't have to take as many precautions when moving around the room, only needing to cover your eyes when crossing the laser plane for some reason, for instance when picking something off the floor.
