Erbium extra footage

[dreasim]

i love more in depth information

[kkonstantinosss2]

I love the professor's childish persistance!

[Yamhal]

if infra red is all around us. would it not be possible to make it a energy source ? just convert the invisible light and low and high energy's to a wavelenght that we can use for power. peace

[douro20]

How powerful is that diode?

[intermission101]

Wow, that was extremely informative. Just one question; where does the erbium ions get energy to emit more photons/amplify the laser pulse?

[saxyweed]

There is a pump laser in the amplifier that sort of charges the erbium glass. When the signal beam hits the glass then it emits the amplified signal pulses.

Please keep posting the "uncut versions" for the geeks such as I.

Truly captivating to those who might not have the opportunity to be immersed in such an environment.

perpetual motion Here we come :)

Solar Power boost, tourch light boost, house light boost, VDU OLED boost, etc....

Great idea.

[CoolMinty]

Fabulous, keep em coming ;) perhaps erbium could be coated with some sort of shark repellent?

[DeanMalenko]

@CoolMinty I suggest human blood

[ArtificialCleverenAI]

I love these vids, could watch them all day!

Are there any channels other than the Periodic Videos and Sixty Nine Symbols?

[brilliantfranz]

this is an excellent inteview, in no way this should go to waste

[777Marlene]

very interesting video.... i didnt know the entire internet could depend on erbium.....i hope we dont come into short supply on that groovy stuff, im addicted to my youtube!......they need to work on a chemical that can make undersea cables invisible to sharks, so the little buggers wont treat them like chewing gum

[wassahilden]

love the extra footage! great work guys and gals

[pin3appel]

the extras are great

[prfctday]

please post all extra footage even if you think it's rubbish :-)

[nottinghamscience]

yes, we'll try to post extra footage from both our physics and chem channels if people keep watching....

[safibn1]

ooh, thank you

[ericsbuds]

@nottinghamscience we will never stop watching!

[asifyoucare41]

i like the extra footage videos! this one in particular helped me understand the concept better. "more sugar in the tea" ahhhh...that i understand

[DeoMachina]

SCIENCE!

Interesting stuff as always!

[IMakeOrWatchVideos]

now only if i had fiber to the house.

[LaughingManRa]

Wow. I didn't know that the Internet used IR light in the fiber optics. :-)

[safibn1]

hmmmmm...pretty interesting...but I see why you cut it out, it was a bit too long...

gotta make things concise for the video to be interesting : )

[batjutsu]

True, but that is why this is extra footage and well labelled as being cut ;-P
