Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Calibration of hydrogen atoms measurement by femtosecond two-photon laser induced fluorescence

arXiv:2404.11909v1 Announce Type: new
Abstract: A new calibration method for H-fs-TALIF is proposed, and the ratio of two-photon absorption cross-sections $\sigma^{(2)}$ for atomic hydrogen (H) and krypton (Kr) is determined for the broadband emission of a femtosecond laser system. The obtained estimate of the ratio of two-photon absorption cross-sections $\sigma^{(2)}$ for H and Kr $\sigma^{(2)}$(Kr)/$\sigma^{(2)}$(H) = $0.034\pm 0.006$, which is almost twenty times lower than the values previously obtained using narrowband nanosecond lasers. This difference is explained by the significantly different spectral width of the excitation line, and demonstrates the need for independent calibration of the TALIF measurements in the femtosecond range.
