Laser fundamentals III: Tunable dye laser | MIT Video Demonstrations in Lasers and Optics

[@michaelbedford2993]

Why is the audio for the whole video mute? Sincerely Canada.

[@Mohabpiano]

1:58 is that a broken conductor's baton he's pointing with?!

[@fjs1111]

🤣🤣 Either the conductor or the baton probably got too close to the laser, that's whats left!! lolol

[@openpalmclosedfist2282]

What is the Diffuser they are using. it seems to scatter the laser into a soft light like from a bulb.

[@ronpearson1912]

what kind of dyes are used?

[@laserhobbyist9751]

6G

[@h7opolo]

me likey. of course, they don't show the tuning in process, just the alleged result. typical scam science.

[@SB-ew8ug]

Not scam but typical boring academia. Check www.repairfaq.org/sam/lasertoc.htm for superior laser education.

[@ARCSTREAMS]

@@SB-ew8ug are all those colours in the same beam and he is only filtering or selecting the colour he wants ,otherwise the colour of the mixture will probably be redish? so for example the red band will be a range and so will other colours right?

[@SB-ew8ug]

@@ARCSTREAMS No, he's tuning the color being emitted in the first place.

[@ARCSTREAMS]

@@SB-ew8ug so you are saying he is making the laser cavity only tune in to certain color instead of all of them at once?

...well what do you think is going on here then? These are literally demonstrations you can do at home with enough dedication.
