Femtosecond Pump-Probe Spectroscopy

[@piyawathKKU]

The presentation is very clear and well organized.

[@giacomopratesi3441]

Great video! Perfect for beginners in laser and spectroscopy graduate corse...good job!

[@JangoJett84]

Great job! When I worked with a fs-pulsed spectrometer I offered to make a video like this explaining it, but was told there was too much other work to do! I think you did a great job!

[@ZeinabMokhtari]

Very clear explanation. Thank you.

[@larsthomsen6434]

This is a superb explanation and examplification of the principles - well done

[@shahfahad1854]

thanks, good job, how i can convert micro joule into GW/cm2

[@siyuchen4133]

Very clear demonstration of the technique!

[@Sunshrine2]

Thanks, lads! Helped me a lot. I saw the 2D spectroscopy for the first time and I was like what the hell? Now I get it.

[@johannab7045]

Excellent video, very clear. Thank you

[@anamfaryal8253]

Can we make this research end graphgs by using origin?? By copy data files from data analysis

[@sam5074]

Very helpful and useful for student who are using the TAS

[@ollinebg]

Thank you very much, just what i needed right now, very good explanation.

[@xiaoweili7071]

It's quite easy to understand! Thanks so much!

[@Mr_Any1]

How to analyze the data from the software.

[@nikhilsen9007]

I have a question @09:50 when the pump is blocked it should show the spectrum of ground-state species but in this case, the spectrum goes away altogether. Why?

[@yitingz3528]

If I understand right, that’s change of spectrum went away

[@syrinegueffrache2223]

Thank you for the video. However, how you define the starting point ? how do you put it ? Thank you.

[@董朔-f1m]

this video said cearly and experiment is easy to understand. thank you so much

[@justinesageka7455]

Very good explanation. Thank you.

[@sandippaul468]

can someone plz explain why excited state absorption was positive?

[@maarijrehman3304]

If I take a screenshot of a particular part of this video and use it as a schematic diagram in an academic paper, how do you want me to cite this?

[@saunakdas1686]

where is the smile button haha

[@asyrafratim3235]

It's really easy to understand

[@JipperdeR]

Thank you for the clear explanation!

[@haizhu5544]

Nice introduction! May I know the crystal that you use for generating the white light of IR and UV range?

[@looksintolasers]

Please make a movie of this!

[@AnupumPant]

How much do the laser and optical parametric amplifier cost?

[@baichhabiraj]

what kind of filter is use to remove 800 nm residue ? What is the spectrum look like without the 800 nm filter( at 8:18 min) ? thank you

[@srinivasmathur8298]

Awesome explanation !!

[@jyothisthomas401]

Excellent !

[@易亮-x8d]

great explanation❤

[@subashkid]

great explanation. got most of it. thanks joel.

[@madhuchakali3753]

it's very good explanation to learning students ...thanks...

[@jeevaraj2327]

Thank you sir, you made it easy....

[@woojinpark4204]

Really awesome! thanks a lot

[@riza9980]

Great explanation, Thank you

[@namesandsuch4539]

Top Knotch Explanation

[@pouria59]

Very helpful and awesome! Thanks heaps!

[@MissMaam52]

baichhabi yakami: We use a short-pass 750 nm filter to remove (or suppress) the residual 800 nm light. Removing the filter will saturate detector.

[@Muck-qy2oo]

How can you measure picoseconds?

[@juanvillegas1626]

They are not measured, but you know the delay based on the total change in length of the delay line, from which you know what time the it takes for light to go through (given that the speed of light is constant and in aire roughly equal to that in air with little dispersion).

[@shuchi340981]

great description..thanks u for posting...

[@bobason456]

The plot is three dimensional?

[@oasisoasis21]

Amazing video thank you

[@parashuramnyaupane5606]

its really really awesome !!!!!!
