6x 405nm diode testing

[ElektroFreak]

I believe you can rotate the diode inside of a meredith module since it's not press fitted (someone correct me if I'm wrong..). In which case you could use your epoxy method and still have the benefit of being adjustable. They do cost more than an aixiz module, though..

So long as it's only the barrel of the Aixiz module that is epoxied; you can rotate the diode holder on the screw threads.

^You mean meredith module? The aixiz module holds the diode with a press fit..

I meant that if the only part that was epoxied was the rear barrel component (which could be cut down); the diode holder screws in to that part. If you applied thermal paste to the threads; you would still be able to rotate the actual diode holder. Obviously this wouldn't work if only the actual diode holder end piece was used. The diode sits in line with the threaded section so heat transfer shouldn't be an issue.

VERY NICE PICTURE!!!

if the diode part is not threaded tight to the barrel you will get another level of "floppyness" as well less thermal transfer loss defeating the reasons why you epoxied the thing in the first place. Yes you would be able to rotate the diode mount, however your "pointing" and "pointing holding stability" would be completely lost making beam combining in a PBS a lost cause...but of course that is only an opinion.

True but, the threads on them barrels are a gozillion percent better than the crap they cut on the lens end You could use more epoxy on the threads, tweak the rotation, stir, add seasoning and leave to set.

Or just use a better mounting system in the first place (just trying to think of positives here )

Very nice picture BTW

I just thought I would toss this one in there for now.

Dis-claimer - banged together in one day.

One of the aixiz module holders is the clamshell type the other is a set screw type.

ALL of my new beam combiners will be the clamshell type. The diode (aixiz diode holder) is isolated from the mount by the thin transistor Sil-Pad material that also serves as a heat transfer and electrical isolation.

The clamshell design allows for you to install diode in aixiz mount and install aixiz in clamshell. you are able to rotate the module in the mount for polarization.


In this design the beam shoots trought the MM-1 (PBS cube not shown but it fits in there)

2.5" high 2.25"wide 1.75" thick room on the back for mounting a 2" x 2" TEC if you should so desire.

This mount offers the full freedom of movements required for optimal performance.

EDIT- That is a quarter not a half dollar

that's a nice bit of work you've done. i'm impressed. i have one of your clam shell mounts and it's excellent.

are you confident this provides enough heat sinking for the diodes? personally, i'd like to see more of the aixiz modules encased by the clam shell, but i've never done any temperature measurements on the diode running in your mount, and it may be just fine.

have you thought about making a place to screw mount the diode driver board (assuming a flexmod or something with similar geometry)?

yes this size can only hold one flexmod, space for 2 x 2" TEC on back shouldnt need more than that. Using the entire aixiz module is no longer being done due to everyone using lasorb...it dosnt fit in the module.

I can make i bit biggger for two flexmods, this is very small, it could be made bigger and still be small

[Laserman532]

Showing flexmod mounting area. I could make it about .375" wider and add another flexmod for driving each diode separately.


Showing back of device allowing for a clear area of 2 x 2 " of TEC, you will never need more than that.

If you have my big clamshell table mount you will never get too hot, at least no one has told me of any problems.
