Dear all,
We are using the continuum IRP frequency mixing unit that produces IR
photons from the fundamental of a Yag (Continuum Precision) and the
fundamental of a dye (Continuum ND6000). Right now, we use the tracking
system to set the mixing Xtal position when the IR frequency is scanned.
I want to be able to bypass this tracking system and replace it by a
home made system based on a PC controlled stepping motor following a
calibration curve.
I would like to know if anybody has some experience in doing such things.
My plan is to put the stepping motor where the wheel used to move the
Xtal manually is and choose a proper gear box. This way, I keep the DC
motor in place and I can switch from the automatic tracking to the
calibration tuning and vice versa easily. Does that make sense?
Any advice about things to do or not to do will be more than welcome as
well as information about motors/gears that would be adapted for this
application.
Thanks in advance
