This is the kind of bright and focused clarifying question that will help OP get their answer, well done.

Helps keep everyone on the same frequency

Speaking of this, the government should build some crazy Rube Goldberg laser that lets a user dial in frequency bands of high fluency output as much as technically possible. Not sure what it could be for, but it would be fun to have (eg asml euv near one end, IR and far IR lasers at the other end).

Indeed, it was most stimulating.

Glad it resonated with you!
