Default Krypton filled Fibre Supercontinuum laser

I just thought I'd share this with everyone.
A UV to IR supercontinuum laser has been created with the assistance of Krypton gas. 300nm to 3100nm.

Here is the link:

Laser Focus World

Now for it to be made handheld.

Very nice, looks like it is going to be applied to microspectroscopy

Oh I misread the metric prefixes my bad, so yeah it is 300nm to 3100nm haha thanks for the correction. Then that means there isnt much pharmaceutical application since most peptides absorb around 300nm

No problem. No probably won't be useful for that, but I'm sure many applications will be found for it, and also probably many improvements as well.

I'm not too sure to be honest. If I can recall, you only need the blue part of the spectrum for them to work, but I might be wrong.

I subscribe to Laser Focus World and have been getting it for over a year, but I rarely have the time to read much of it these days. Just scan the articles. Hopefully all that will change in the next few months and I'll be able to read more than I do now. Thanks for all who brought this here. I found it interesting.

On a separate note I came across an article on BICs in an electronics magazine and a search lead me to LFW, I often read there online but don't subscribe, I don't know what may come of this but it's interesting.

I was wondering how one could store light information in a BIC that, instead of plugging light leaks, destroys it through destructive interference. I guess that is a problem for future designers.

Default Re: Krypton filled Fibre Supercontinuum laser

Binary at the least, it's a question of what can be printed smaller, I know an electron can absorb and emit photons so I assume photons are smaller than electrons, in the end a jump drive may hold trillions of bits of static photons rather than electrons.

Now what I want is the gamma laser they print the things with.

Default Re: Krypton filled Fibre Supercontinuum laser

RCB, I never thought which was larger, a photon or an electron, so I went searching, found this answer:

The electron is larger. Although it has a small mass, a photon has no mass. A photon is the smallest unit of energy that can exist. It is the carrier particle for the electromagnetic force.

Cyparagon, where are you?
