for the master microcontroller, need four outputs, one input

for the 2nd microcontroller, need 1 input, 2 outputs

we might need a ampere increaser between the laser diode and the microcontroller b/c microcontroller don't supply sufficient amperes. the laser needs some 67 mili-amps but the microcontroller only got 10-20 miliamps.

the distance b/t lense n laser can be variable, to prevent too much distortion due to non-vaccumed space [refraction n diffraction], the distance shouldn be no greater than 3 cm or even less.
distance b/t lense & fiber entrance should be the focal length of the lense [from the the lense surface to the point of focus]

in terms of the LGDW piezo holder, i'm thinking of using a piece of rectangular flat platform. to my observation, all piezo for STM are somewhat soldered on. therefore a 5X5 cm square should be sufficient. of course,it will be able to move in XYZ direction.

in terms of the tube that is gonna deliver AL mist, i think a transparent, plastic tube with a diameter close to our lenses' focal lenth should be good. of course, we are gonna drill a small hole on the tube for laser entrance and particle to escape.
