I might inquiry if you have any plans to market the diode drivers. I'd be keen to purchase, depending on the price.

Here is the complete commoditized digital driver.

how do i get my hands on some of these drivers?

But you must be very clear about the configuration parameters of your laser.

I decided to use stainless steel for the stator and rely on axial preloading and a close fit to minimize movement. I chose a ferritic steel (1.4742) to reduce coercitive hysteresis and magnetic reluctance.

1.4742 ist ferritic, but has a very high amount of chrome (17-19%), so the possible magnetic flux could be less than using ordinary cold rolled steel.
Just use simple cold rolled steel (or for example 1.0715) for the stator and your scanner will be much faster.
