new build 2.5w

**VJ AIWAZ** · 05-31-2009, 05:24

i started to build or rebuild my melles (laser power) system in a bt500 case from OSLS

i just got my melles back from a fresh rebuild new diode and crystals

but they lost my damn collimator so they fixed it with an optic from a laserscope so now i have a 2" spot from 25'
my question is what is the divergence now and what was the original i cant remember it was the old LFI design

Hmz, can't you make them pay for a replacement? I mean, they lost it ...

My 58GSD is something like 14mRads, but that's with the collimator.

well it was a friend of a friend and he says it was never there and my friend dosent remember but believes i never removed it so he is the one who came up with the laserscope parts and the bt500(case) as a replacement/compensation

is the 58gsd the dual beam model

this was a dual beam but with the repair it was converted to a single beam withe the replacement of the angle mirror with a flat one

It's dual. I keep hearing about modding options. It would be really neat to somehow get a polarized, 5 watt single beam out of it and shoot it through an AOM for blanking. (I have a NEOS 4-channel, ironically.)

well thats the plan

this one had a 20w pump diode put in and my power supply was the trouble so next round we are gona try a 40w and a new power supply and some new tec's but as of now i have a stable 2.5w and a AA AOM

also i got this aom on ebay that i thought was broadband but now im not so sure it says its for 1064nm

but in the specs it says its 488nm-635nm does anyone have a clue

I don't see why they would list those wavelengths if it couldn't modulate them.

Perhaps it will pass those wavelengths with only minimal deflection?
