Dye Laser pumped with DPSS...

[Stoney3K]

you take a copper tube, you drill plenty of holes in it, you stick bluray diodes in them, then you put your dye tube in the copper tube

that was an idea I had some times ago, but surely this wouldn't work!

Somehow it does sound a little too simplistic to work anyway. I'd be interested in learning about 'other' laser types (besides DPSS) from the physics POV, and what it takes to make them work. DPSS is really nice for show use because of its compact form factor, but from a lab perspective it's little fun. Gas or dye heads with loads of plumbing, huge amounts of three-phase current and page-long startup checklists are MUCH more challenging.

Those peaks at 435 and 440 nm are interesting, because they obviously can't be from two photon absorption. The authors of the article don't even bother commenting on that...

I'll read it tonight, but that paper is a TANGLED MESS...

Any tips for a poor mans fs laser?

Looks like Phen Green is $160 per milligram!!

Not really relevant to the thread, but would be a very interesting topic for another discussion! I would be impressed if people could pull it off.

a - Why?

b- How would measure it?

c- What do you need it for?

a - Why?

Why not? Would be a very interesting project!

b- How would measure it?

Autocorrelator?

c- What do you need it for?

Who cares!

[Laserman532]

do you have a fs autocorrelator?

I guess it would be an interesting cocktail party discussion.

[Laser Ben]

I can probably find one if I need it.

well you will need one to build a fs laser, its not like you will build a fs laser then go find an autocorrelator standing by for pictures!
