Ever had this happen?

Ok I have a 473nm. laser that came out of my old laserworld laser.... Well when it was in there it never would do more than 20mw.. It says its a 50mw... So I got it out to mess with and it wouldnt do more than 10mws, even after cleaning it. Well the other day I picked it up to move it and I heard some thing banging around inside,pluged it in and nothing... well after getting it open, I found the crystal and the copper top, had fallen off.After a good cleaning, and a drop of glue, and so alinement.. It now does 50 -75mws.!!!! Just depends on the room temp. Anyone ever heard of this before?
And some nice pics. of the guts!
enjoy!

You got lucky, Matt!

Obviously the cavity wasn't aligned worth a damn. When it fell apart, you had to re-align it. And without any real work on your part, it looks like you nailed it!

Congratulations. Mike (Mecheng3) will probably want to have a peek inside that thing at SELEM now that you've tweaked it.

Laserworld you say? hmmm. It's a good thing that it didn't damage the optics or diode while rattling around. It's a good lesson: if one hears a rattling sound inside their laser head, DO NOT SHAKE.. carefully investigate.

I haven't had such a lucky break, however I do find it odd how similar that laser is to the BWTek ones that have been on ebay for super cheap recently. They have the power control set for ~7mw, and will put out 20-30mw when you take off the photodiode (causing the driver to run the diode at full current, ~2A) It does have nicer beam shaping optics after the pump diode, but the laser cavity itself looks identical. What current does your system run at? http://www.photonlexicon.com/forums/...ad.php?t=11161

I am not sure if all of the small 473nm lasers are set up that way, perhaps the laserorle is a clone of the BWTek?

I haven't had one fall off but I have tweaked shit loads of power and a better beam profile by spending a couple of hours aligning the cavity (473s and 532s).

oh it happens i was doing a new years eve show at a large nyc night club and the bass rattled my vanidate loose on my 3w melles
and after that we had no show

but at the time having one melles was a big deal (it was over $10k )i didnt have the funds to own a back up at that time

I wasnt sure if it would ever lase again.. But thankfuly it did!!

And yes if something is floping around inside a DPSS laser...Dont shake it!!

Your right they do look alike...hmmm...

Im not sure... Ill have to find out... Its got me thinking too....

Yours looks like a standard CNI MBL-III-473, while the B&W units are similar but with anamorphic prisms instead of just a lens for pump correction.


EDIT: krazer already mentioned this.. my bad.
