Measuring the pulse width of a Laser using an Interferometer

[@Florian-px5up]

Excellent instruction how to align Michelson Interferometer with retro reflectors.

Thank you for your posting movie. I learned about alignment for my setup.

This measures transform limited pulse duration, not real pulse duration. You can measure the laser spectrum, and do a Fourier transform, and then you can get the same results.

hi! i like your video, but i have some questions, do you use autocorrelation? can you make phase retrival and recover the shape of the pulse?

[@hoofheartedicemelted296]

Mr Peiris do you have any videos on setting up a Phase Conjugate Mirror using Four Wave Mixing? Thank you sir. I am interested in BaTi03 crystals to produce nonlinearites, and Time Reversed Wave Front using RetroReflectors.

Whats your input power ?

[@xwj8245]

where is BBO crystal

[@josehernandez5671]

Hi... where can i get taht kind of lab equipment?

[@garak55]

Thorlabs. They also send candy with each order.

[@davidredish]

Can we use a simple beam spliter instead of a Cube?

[@xwj8245]

yes

[@xwj8245]

yes, cool. but it will introduce many dispersion

[@245632111]

Does this technique work for femtosecond lasers?

[@xwj8245]

yes! fs laser is the same

[@roadrunner6653]

Yes, to measure the coherence length. Not to measure the pulse duration.

fiddling with stuff, with bare hands lalal alalal ... many moons later ... lalala ... 0.6ps period. - WHAT!!!??? \OO/ - Science, bitch. lol)))

[@Molb0rg]

generally awesome))
