Submission Rules

Posts must be relevant to lasercom.
We like questions, news, discussion articles, published research, course content, educational resources or videos about Earth or space-based laser communication.

Comment Rules

The rules are pretty damn simple:

Be respectful to other users.
All users are expected to behave with courtesy. Demeaning language, sarcasm, rudeness or hostility towards another user will get your comment removed. Repeat violations will lead to a ban.

No misinformation.
If there is a question, don't just 'make stuff up' unless of course it's obviously a joke. This rule is simply to avoid assertions of pseudo-science or incoherent / uninformed rambling and keep the sub reliable and informative. Sometimes cutting-edge technology is pretty crazy and hard to believe. So when making wild assertions, we encourage you to post links to supporting references, or use valid reasoning.
