Anyone have any thoughts on how the 573nm process works? Possibly directly doubled from 1146nm?
I took my module apart to see whats inside. The aluminum section is threaded onto the brass base with glue that was very hard to break.
The crystal assembly looks a lot like a DPSS green. A little pac-man style brass holder with a lens glued directly on top.
Unfortunately due to the glue holding the crystal in place I can't tell if it's a single piece or multiple.
Using snap ring pliers in the two holes in the base I attempted to unscrew it, but I couldn't get it to budge. So I chucked the whole thing in a vise and started filing away at the side until a hole was uncovered.
Using a small screwdriver I was able to the pry the base out to reveal the C-mount diode with FAC. It was a very tight interfereence fit and took a lot of force to pry it out. Despite my best efforts to be gentle when removing it I somehow still managed to damage the laser diode and tear the bond wires going to the die so it no longer powers on.
The C-mount is mounted right out to the edge of the base so it makes sense why these modules couldn't be made smaller with these pump diodes. I would love to get a replacement pump diode in 5.6mm and rebuild the module into a an old DPSS green module for a 12mm 573nm.
