I cannot admire you as much as you deserve! you and your way of teaching are excellent!

thank you so much that was helpful 🤩

One of the clearest explanation. Liked and subscribed immediately

what a legend

Uberkrasser vid👍🏾

I wonder why they need to make the analysis of stability on an equivalent lens system?

Excellent 👌

Sir, Your lecture is incredibly informative and helped me gain an intuitive understanding of Q Switching. I have one question. Pardon me if I missed something out from a previous lecture, but as covered by you, Continuous wave laser achieves much deeper penetration of a material. So, why don't we just use Continuous wave instead of pulsed LASER for achieving penetration of a material.

What is ml in Schleimpflug condition ?

Thank you for such a good explanation. It was really very understandable.

It was Gordon Gould who first thought up the idea of the LASER in 1957 and gave it its name.

Like the Chinese that have a Miner but can not handle Element 115. So it only works for around 5 Seconds.

The best video , I have not found a concept as good as this in other videos! excellent

Klar und deutlich erklärt (obwohl mir Deutsch lieber wäre :) )... vielen Dank.

Really awesome presentation

How does this relate to Airy Beams .. is some element of the propagation as such? Thanks

主要是在讲解光纤激光器的发光。

Hi

Super clear and comprehensive🎉

Perfect videos. In 17 min I got what I learned for a week in my university😂

5:37 The location of the beam waists (w1 and w2) in the right image, where the far-field divergence angle is equal, should be interchanged.

this man is too smart for my dumb brain

the ones o know better are the ones o explain it better too, great video!

they use lazer drilling in the US DUMBS military bases

a really great series of lectures. Thanks!

Great lecture! Could you share where the figures are come from? citations?

This is a great explanation, thank you

It is very good

I’m working on a project would you like to help me!

I don't know how I came here, but the material is really very fascinating to me. Thanks Prof.

Thank you very much!

Thanks for great explanation regarding Laser welding !

thanks professor

Excellent presentation.

Gaussian beam is a kind of eigenstate. This is why we analyse on it. It is not that easy to get ideal parellel light.

Can you explain Wakefield lasers?

Outstanding lecture..

greating from Mousl Iraq 🇮🇶

Loved the waveform/wavefront demonstration in the beginning.

Professor can you make a video on q guassian and super guassian beam propagation 🖋️it will be very helpful

Such a good channel. Glad that I have found this. Thank you very much for the clear explanation that makes the difficult topic sounds so simple.

I wonder how a laser light would react if pointed inside a "Tesla turbine." Would the light also have a sort of "Boundary Layer Effect" following the fluid path (water) ultimately reflecting out? ..

I just love the beginning: it is an eigen solution of a resonator" we all due respect Sir but this is not a straight definition

Very well explained thank you

Thank you. This is very helpful

Thank you, amazing explanation. Very easy to follow
