Hi Charlie
A lot of experimental / pioneering work is being done by others using low powered (1 Watt) diode lasers in this thread http://hobbycncart.com/forum/63-151-12937-16-1362353174
Because the rate of burn (apparent laser power) can be varied by changing axis speed there are currently two software programs being developed which will create the required Mach3 GCode from a BMP image. Your solder mask could be considered an image so it is more than likely that it could be produced by this method and without the need for PWM control.
Just a thought.
