6x 405nm diode testing

[chad]

HI guys just to set the record straight.

NO, I did not invent the little flexure mount. I don't know who did. I tried to find out because I wanted some, and was unable to find any to purchase.

Dave beat me to the punch by a couple of weeks. His are a little smaller and made from brass. Dave did offer to send me his files but I just sat down and designed my own in sw. This actually works better because I did a little fine tuning after the initial prototypes, But It was nice of him to offer!
And I don't think Dave invented them either. I have a feeling he ran into the same problem that I did, He wanted some and couldn't find any so he made his own.

Dr.Lava's current red modules are actually basically my design. In fact I made his first batch. He then tweaked the design, improved on it and had someone else make his current run. I don't care in the least. If I have something top secret It won't get posted here. I am glad he improved on it.


Back to the mounts, As to who actually invented them I still don't know. Flexure mounts of different kinds have been around forever so this exact implementation might be novel but flexure x / y adjustment is not.
I put 45 degree chamfers does that mean it is a newer novel-er design???

Like I said I needed some, I have the ability to make some, so I made some extra in case someone else wants some. I sure as hell am not going to become rich from them. If I can re-coop the materials and some of the time I put into them great, Maybe I can throw some of the money back at the $110,000.00 machine I made them on.

This board has a very strong DIY standing. We have software people, hardware people, electronics people, experienced laser people, and noobs and everything in between. Everyone has their own opinion of how things should be done and as long as we are all having fun and learning 'the right way' doesn't matter.

Just my opinion, and you know what they say about opinions...

I still say it would be simpler and more practical to just stick the aixiz in a block with a set screw and isolate the block with heat-conductive pads, but you're absolutely right, that is only an opinion.

Another option is diamond heat-sync compound which is electrically non-conductive. I think a flat surface would be best for its use, but it may work around an aixiz casing. The one thing I was worried about was it rubbing thin etc just a though. http://www.heatsinkfactory.com/ic-di...m-p-16605.html

I might pick up a tube sometime for testing a red, heck it's thermal properties alone make it appealing without noting the electrically non-conductive properties. Maybe not the best option but another on the table.

you mean this type of heat-conductive pad?

I don't think I'd use something that didn't work well in your own past experience, no.. I think a thin sheet of mica would be the ideal medium, and there are other types of thermal tape/grease.. of course, the quality of the surfaces where they meet should be very high.

Given the scale you're working at, even the little piece of mica that comes with transistor isolation kits should work great..

Look, it's your own design, you can do with it what you want.. I just think that an inability to optimize output is a severe limitation. As was stated before, it takes a VERY tiny off-angle in polarization to lose some pretty significant power through a PBS. When dealing with such precision, being adjustable is a must... IMO..

but the bottom line remains: it's your design. I'm only stating how I feel about it.

Like the chamfers, nice touch. I have seen it done but not on both sides.. makes yours a very universal mount

Amen
The great thing about forums is ideas can be thrown around, criticised and often improved by styeps 1 and 2 - a good thing

lol im only messing that stuff i had was crap but u get my point

Like this? I used one of Laserman532 mounts, drilled another hole for the axiz and set screw. Works pretty good for me.

nice mophead, that is the first time I saw that. good job. That was a very creative modification of my hunk of aluminum. my next series will be an improvement. too much stuff...too little time.


no pissing match or scoreboard is necessary. The ability to rotate diodes, no matter how you mount them is a desirable feature of ANY design.
