Happy 5/20!!
So I have a few weeks off, and have decided to dedicate my time to a well needed laser marathon.
Today, I wanted to start the marathon off with something small, so while digging through my piles of junk, I came across this WL Fusion laser. I bought this used a few years ago, and the output is fairly unstable. Considering it is 5/20. I decided to throw in an Osram PL520, but run at low power to blueshift the wavelength.
I started by pulling off the button:
Then I used a vise to pull out the module. I nicked up the pain a bit, but oh well.
Here is the disassembled module. I decided against sacrificing this module for the switch, as the module is CNI made and I may find use for it in some DPSS projects in the future. Instead, I just found another switch board used for pen hosts.
Here is the switch board soldered to the microboost drive, which in turn is soldered to the PL520 laser diode. I don't know what current it is set at, but I dialed the potentiometer until I got 15mW of output.
Next I pressed the whole module back into the host, and made final adjustments to the focus of the (acrylic) lens.
Here is the finished product!:
and of course, a pic of it running!!
The color of this laser is definitely more blue than my other 520nm lasers, but I am away from the lab so I cannot get a spectro reading for the next few weeks. Regardless, this was a fun build and was a nice start to the plethora of projects I am about to tackle!!
BTW, if anybody needs help with a pen build, I'd be happy to answer any questions. :beer:
