Shining my Blu-ray laser at highlighter juice

I got bored and decided to shine my 405nm Blu-ray laser at highlighter juice. I was hoping for a yellow dot but the juice does not transmit the beam very well, even with a 445nm.

If it transmitted the beam well you'd be even less likely to get a yellow dot. You need to make the dye lase by pumping it with another laser - that way the dye will emit a yellow laser beam - however - you'd need to pump it with a high power pulsed laser such as a TEA Nitrogen laser for it to work. A CW, relatively low power 405nm or 445nm laser will not work. I say relatively low power because even home made TEA N2 lasers can reach peak powers into the 100s or even 1000s of kWs.

Fluorescence is fun to mess around with on its own anyway.

Couldn't that burn steel? That's a lot of power.

That's my favorite thing about 405s.

Typical pulse widths are <30ns (as short as a few hundred picoseconds) - It's a high peak power, but there typically isn't a whole lot of energy involved.

That said, larger TEA N2 lasers should be able to punch a hole in some thin steel!

Try adding a small amount of laundry detergent to plan water, I did it and got some really interesting results.

This is a 532nm

Im going by these pictures because I didn't actually look at it even with goggles. I used blue tide btw.
