Default How Lasers Actually Work (Just a link to a good web page but wanted to pass it on).

I thought this worth passing on because it has some nice illustrations.

How Lasers Actually Work | Notey

Just some introductory information regarding how lasers work.

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

Thank you so much for that link, I've bookmarked it.
Looks great, I'll read through it when I have time to enjoy it all.

Cheers Mr A.

For God so loved the world that He gave His only begotten Son, that whoever believes in Him
should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.
(Romans 10:9-10)

Interesting stuff, though most of it concerns gas or solid state lasers, not so much laser diodes.

For those reading for educational purposes: In diode lasers population inversion is achieved by an electrical field.

A rough analogy is that a HeNe laser is basically a neon sign tube with mirrors on its ends, and a laser diode is a LED with mirrors around it. Ofcourse that is not the entire story but perhaps a concept to keep in mind when reading that article.
