Hi,

I just thought I'd share this with you all:
I was reading the latest edition of "The Engineer" (UK Science Periodical) and there was an article about a new type of UV laser diodes being designed. Supposedly the "shortest wavelength ever made by a diode" or something.

Anyway, I scanned in the article below.


Dan :-)

Edit: Upside down image fixed! :D

Yeah! - Get Greg or DDL on the case in a few years!!

Also, I laughed when he stated in the article "At 635nm the capacity of a DVD is 1GB" Eh??? lol  ;D
 
blu-ray was something like 24gb IIRC? Getting kinda close to xray raditation ;D ;D ;D and xray diode, count me in! ;D ;D
 
Problem with messing around with UV sources, high intensity UV can manipulate DNA IIRC ? In other words - INSTANT MUTATION...erm....I think these things will be rigged to self destruct if the DVD burner case is ever opened LOL

ya i can see it now some newbe pulling his 377nm from his burner and starting a new diy project. will need a warning sticker DO NOT STAND IN FRONT OF BEAM WITH REMAINING BODY PARTS HAHAHAHA

That's high intensity short wave UV can damage DNA. A burn from a UV laser would be more like a sunburn than a conventional burn.
 
Well, you wouldn't see the dot for certain.

But then again, on the beach, you can "sign" the people that used no sunscreen with a laser like that...write something like "Sunscreen helps...if you use it" or "Cancer kills!". Then collect your share from the sunscreen factories...

b2t: still sounds kinda cool, get all sorts of fluorescence...maybe frequency doubling will work easier, so you could habe a 674nm laser...is that great?
 
It's already possible with DPSS.

It'd be dim as those 808 pens, but I'm pretty sure you could still see the dot.
 
i dunno about these diodes. maybe they do work but it will be years until production. just liek the nichia diodes..
 
Any shorter wave light gets my attn. right away! I am way into the Fluorescent and Phosphorescent stuff. I can't wait 'till I can get <340 nm and start the search for fluorescent minerals by the tons! :) ;D :)
 
Scopeguy is right on. We all know the potential harm any laser can do when suffieiently concentrated. We here on LPF warn everyone all the time. Please allow those who understand the risks to proceed -- that's how advancements are made - aks a few astronauts !
If you can't handle the dangers -- don't do it. I always warn about high voltage risks with CO2 and NdYAG systems.
Life is at your own risk.
