Half a watt of 457nm anyone?!

Laser_Ben · Dec 28, 2008

Probably my favorite laser I had!
400mW 457nm Single Longitudinal Mode Dual Beam Melles Griot

Here's the rest of them:

ooooh nice deep blue ftw.

Is there any chance of a 405-457-473-488 or any combo thereof comparo shot?

That is a REALLY nice color!

I have had all of those at one time or another, but not at the same time. I have a 430nm Coherent unit which i am working on. See my next post in this forum.

is there a reason for it to have 2 beams? or are they combined when you focus it?.. (lol sorry im fairly new to lasers in general.. just wondering..)

I would kill for one of those melles dual beam units... I hardly ever see them for sale and when I do they are ridiculously priced (well, for me anyway, still a fraction of the new cost)

How in blazes did you afford one of those?

Laser_Ben · Jan 1, 2009

That is a very good question!

Selling drugs?

;D

Nice laser BTW. We need some good fog or smoke pictures.

That laser makes me want to cry :'( :'(

What type is it, DPSS? Unusual wavelength you don't often see - I'm sure that would affect the price every bit as much as the power!

I know a few of their greens are dual-beam models as well and they are combined and sent out at a right angle to the head. Does this have a set of similar optics?

Ah SLM dual beam, perfect setup for holography or other interference related projects. And the Melles linewidth is probably on the order of 10[sup]-5[/sup]nm or better allowing at least a 75m or so coherence length.

Schreken, the 457nm is DPSS and is actually quite popular in the scientific community.

beautiful laser

laser ben likes to go dumpster diving (or skip skipping if you prefer

)

Yeah, dumpster diving is the best! You get so much amazing stuff!

Here is a bit of info explaining the theory of dual beams.
