Mysterious red laser light from 532nm laser?

[tung]

This is a video of a 532nm laser's dot on a white phone in which I place a red filter between the cam and the green dot. The red filter makes the green dot appear red. My question is: What is the source of the red laser light?

Fluorescence.

Fluorescence.

Makes sense...thanks!

What happens to the beam on the other side of that red filter? Does it appear collimated at all?

Am I the only one you read the title of this thread and panicked? I instantly thought, don't look into the IR light!
Yes fluorescence is the answer, thankfully.

Nope, I did the same thing.

 

[CurtisOliver]

I'm glad I wasn't the only one then.

 

[Encap]

I did same thing lol

 

[CurtisOliver]

That is when you know you are doing a good job.

I had a sorry your 532 module loss eulogy all written up.
Edit: I'm sure tung the OP set us up nicely with that title:beer:

GSS, . We were all to quick to think the worst. :crackup:

 

[Alaskan]

I'm a slow thinker, didn't cross my mind that was what it could have been.

 

[CurtisOliver]

Its ok Alaskan, it could of been anything. Just that is what first came into my mind.

I saw this thread when it was minutes old and my first thought was someone was looking into the defective laser and seeing infrared light. Then I read the OP and before I could answer, diachi had beat me to it. I thought it was a dead thread at that point, so I didn't answer. I guess we are all looking for a pertinent thread to answer having so few of those these days.

Agree--we are all used to "whatever can, usually does"--with a few exceptions +
with recent instances everyone is on orange troll/spam alert.

:can:

 

[CurtisOliver]

Well yes, we do have our reasons.

whatever can, usually does

That phrase is usually accurate. On alert does cross my mind.
Paul, I too was going to leave this thread, but I was just interested to see if others had the same thought.
