Ok I tried to search up this answer on the forum before posting but with all the conversations around water temperature, it was not easy to find.

Can anyone tell me what the temperature of the laser is at the focus point?

Assuming laser is in good working order and properly aligned and focused.

It depends on what’s in the beam and for how long…
Why do you want to know? :slight_smile:

Ok so I was watching a video on metal printing using laser and was wondering if a similar process would work with silica sand to create glass with laser.

if you can crank up the power just a bit, you can make some cool sand art - https://blogs.scientificamerican.com/but-not-simpler/what-really-happens-when-lightning-strikes-sand-the-science-behind-a-viral-photo/

Can’t you just put a thermistor on a piece of black anodized Al and measure it?
