Aixiz 532nm TTL modulated laser lab module
I figured I will do a short review on this unit, as the thing that I wanted is the TTL capabilities of it. I am not a fan of making my own low powered DPSS systems just because of the hastle and cost, so I figure I will buy this particular one, due to its power and TTL capabilities.
Lets start off I guess, this is my first review, so applogies if something is amiss.
Shipping:
Aixiz shipped this laser quite well, it arived in anti-static bubble wrap, both around the entire box itself, inside, and individual protection for the module and the driver board.
It took about one week and a half to ship, I would have liked it to arived sooner, but such is shipping and this time is quite acceptable and typical, not much anyone can do about that.
The packaging is very well done and I am happy with it.
Now onto the fun part, the laser module:
The laser module is made of two pieces of aluminum, one holds the pump diode, ND:YVO/KTP and expander assembly, the other holds the lens. There isn't much else inside the module, and isn't worth poking around in there, so just leave it alone.
The driver requires 5VDC input, and modulation is your typical 5V/0V.
The driver is fairly good, however one thing I have an issue is is that the TO-220 on it is heating up quite a bit, I have no idea what device it is as the part number is whipped out. either way, a small heatsink fixes the issue (even without a heatsink, this driver doesn't heat up too much and stays in normal tempertures, I just like to run mine cold for longer life).
On the board there is also a multi-turn potentiometer, where power is adjustable to barly lasing, to full power (you cannot null this pot, it has mechanical limit points).
So here are some mandatory beamshots of any review
Comparing it to some pens I have, this thing is definatly not 15mw (as the site stated IIRC). it outputs more like 30-40mw (I can feel some heat from it when focused down to a fine point). I am going by eye, I don't have an LPM to confirm.
Now, to test what I got it for, I whipped up a quick variable frequency oscillator, just to provide a +5V/0V square needed to modulate this unit although, this one can be modulated from both negative and positive inputs, respective to the driver's inputs and common ground.
A bit crude, but it works:
I shot a quick video of the laser bieng modulated and scanned by my X-Y galvos.. (random inputs, nothing in particular). it seems my camera has issues capturing the intensity of this thing on video, but this is more or less close to what was going on.. those waving lines are the result of the random scan signals and the TTL modulation of the laser.
Thats more or less my review, I hope you have enjoyed it. I can really recommend this laser to anyone, either just as a nice stable lab module for fun, or for low powered scanner use. (I realized much better can be had, but this is really good for what it does, its power output and the price.
For my experience with aixiz, the shipping, support, and quality of product, I will have to rate this one at 5/5.
(not that you need my confirmation to know aixiz is a decent company, but thats just another vioce that supports them now )
If anyone has any questions they want answered about this module, feel free to post it in this thread, should I have not gone over something.
