I don't know a lot about lasers and orientation!

But yeah, tunable lasers cost a lot of money. Like, price-not-listed-call-us-for-a-quote prices. As I understand, argon ion lasers could emit most of the frequency spectrum.

Definitely going to revisit this thread if I happen to run into someone who knows more lol

This is what a laser does, through "stimulated emission" (i am not joking, that is what it's called) of electromagnetic radiation!

Also look into "masers" or "spasers".

But other than that, no idea. I speculate it's really difficult to do that within the ~500 terahertz frequency (visible light?) Wifi radiation is at ~5 gigahertz and radios are at ~kilohertz.

All the light emitters I know of use fixed-frequency emitters. Phoshpors, etc.

https://en.wikipedia.org/wiki/Tunable_laser It seems there are some "tunable lasers", and reading on these shows me some (new!) research into tunable phosphors: https://pubs.rsc.org/en/content/articlelanding/2018/dt/c8dt01991f

The abstract cites displays as an example!

I like this question!

yeah!

This value is too long. It should have 300 characters or less.

u get this error if u try. i have! :D

POSTS FROM THE FUTURE:

JSTPST WINS "BEST PLACE TO POST OF ALL TIME" AWARD

STILL REMAINS SMALL AND TIGHT KNIT

Update: I am now seeing people posting on smaller, tinier, sillier social medias for advice, because they'll get TOO many replies on Mastodon. Amazing

i think about the medulla oblangata regularly

i literally think ive only seen this on the g*biverse

u should check it out again!

EDIT: nevermind i just went on the federated timeline and saw someone saying basically this

haiiiiiii x3333

thank fucking god

Oh!! I used to keep track of these. Here's a list using the same methods I used prior:

Postmills:

• Raddle, of course
• The one with neo-nazis (r****e dot pw).
• A Chinese frontend dev who uses a Postmill instance to post a GitHub instance.
• https://cyber.report/, an invite-only Cybersecurity news site, similar to the above.
• A Portuguese language TTRPG forum
• A few smaller ones that seem to have no posts or members (kini)
• jstpst!! just post is the very best place, the very best place to post, just post is the very best place, the very best place to post
• jstpst is the very best place
• the very best place to post

Ones which went down

• Babble (no idea what it was tbh)
• gamergrounds

Secret deployments:

• eye2p
• "dntpst", which nobody can access, not even the admin.)

I haven't checked any Postmill mirrors on the Gits to see if they point to existing instances.

i also buy oolong tea more than i used to, and i credit 1. you and 2. oolong tea being tasty
