I have read the FAQs... and tried a search, but didn't see what it was that I was looking for... but anyway - here is what I was thinking of doing. Oh, and 'did'.
I had a dead greenie (dies from pot-modding) :
and I rather juicy 808 nM (At least that is what I thinkit is...) that I pulled from a 36X CDR drive. From what I have read here, the 808nM LD shines through the Nd:YAG, turns 1064nM, then goes through KTP to yield 532nM. Got it. Alignment of crystals is critical. OK. I hear ya.
So what I wanted to do was to yank the 808nM that died out, and pop the new, more potent 808nM in, and in theory have a more potent pointer (don't take that out of context :lol: ).
So I took a run at it. Surprise! It didn't work. :'(
Ok, it was not a surprise. I was pretty sure there was something that I was not considering... seeing as how I am a mechanical engineer dabbling in the EE world (or is there such thing as 'LASER engineering' now??)
I figured one of the following things occured:
*The crystals were bad as a result of pot modding? Long shot, but who knows? Obviously not me - or I'd not be suggesting it...
*The crystals went out-of-alignment when I took the old LD out?
*The diode I put in was not actually 808nM?
*Some other nano-consideration I did not realise??
Pardon the extreme newbness here - but I am literally starting at ground zero here. I am a guy with a great technical and engineering background with a couple of laser pointers, some basic optics, a pile of IR laser diodes, and an ESD protected 'clean' lab to work in. I want to learn more. My desires for learning more are mostly just to increase my 'play' knowledge to be honest. You know, that knowledge that you might someday use... but is mostly just more 'hobby' knowledge than practical working-knowledge.
Anyway, I look forward to learning more from everyone!
