Hi Everyone,
As some of you may know. I purchased a couple of these tiny RF pumped CO2 lasers at a local swapmeet last week.
Well, I just started reassembling the power supply for this laser and having no experiance with RF supplies,,, I have a few questions. Here are a few pics of the laser head with the RF amplifier I just installed along with the RF pre-amplifier/modulation board.
So, I installed the RF amplifier board onto the laser head and used solid copper wire to run the connections along with covering the sharp connections with hot glue to keep the RF from dissipating.
Here are my questions.....
It seems I need a fuse on the board that powers the large MOSFET amplifier. What is the value of this fuse supposed to be?
Is the input on the amplifier power board +12VDC?
Is this where the pre-amplifier RF signal goes?
Here is the pre-amp board. I'm guessing I need +12VDC for the modulation for full on. Is this correct?
What is the other input and voltage? Is this an interlock or something?
Here is the other end of the board. I'm guessing the main power for the board enters here as +12VDC and the RF output exits via the BNC connector and connects directly to the laser head amplifier.
Any help would be greatly appreciated.
Thanks!
Adam
