Beautiful Berlin Lasers

A second choice would be a Jenlas or two ... See:

Damn Steve,

You do know where to find nice laser articles to read

Thanks for sharing

It was this particular article that aroused my interest in solidstate lasers about 8 years ago.

I read that article about 5 years ago. That's a serious RGB setup.. I'd absolutely love to see it in action! I would imagine passing the final whitelight beam through fiber before output would give an ion-like beam rather than clusters of superimposed beams as produced by dichro combining alone.

Hello,

for this job several AR/KR Mixed Gas Lasers and several JENLAS RGB (628nm, 532nm and 445nm) have been used.
The Jenlas Laser are modified to get max output at 628nm or 445nm ! For get Laserdiodes or OPSL - this Jenlas are running
in TEM00 mode and have a great beam quality.

Maybe Laserman532 can make a SUM-FREQUENCY GENERATION DIY kit

LOL

Hey Marco -

Thanks for chiming-in... Yeah, I was wondering, too, about that much 445 - that it a LOT of 445! Beautiful!!

Well, there we have it - Bart, you and I each owe Steve a pint.... He said Jenlas first.. I for sure would have gone with KTP/Dye, since you can tune the dye and easily get those colors, and more-likely get that much power vs a fiber-laser, but sure, the Jenlas makes more sense...

I have this pic from years ago - I believe it is the Scheider - did Jenlas buy them out / take it over? Or are they one and the same? Either way, brilliant use of solid-state technology...



..but great to see Ions being champions, still... Thanks for the posting, Marco! And please pass along to your mates our profound admiration for such a great job... very, very cool werk!

cheers..

yess, good eyes jon- seems the ions are alive and well on that project-

Hey P -

yess, good eyes jon- seems the ions are alive and well on that project-

yep, only way to get that much cyan / blue... with that caliber of beam-quality... but Dang - 8.5W of 445 - that had to look Sooo amazing live... the pix and videos look rad enough, but that is such a bitchin color in real-life...

peace...

Although the effect is stunning, I feel they cheated on the orange and Yellow line.
If you've got acces to a few jenlases, why not create a rainbow of 15 composite coloured beams ?

No question about it that one argon alone consumes the amount of power that could supply an entire array of Jen's.


Wouldn't 10+Watts of 593 and 561 be jawdroppin' ?

Hi,

if you have a high power q-switched Laserscope 532 you can also use a
Raman-Cell (with internal gas return) filled with Deuterium to get bright
red (strockes) and blue (antistrockes).
With such a setup you will be able to convert arround 30-50% from
532nm to ~630nm and 10-20% from 532nm to ~457nm
