A quick question. I have a 35mW He-Ne laser and I want the beam to pulsate
with a freq of 10MHz. What kind of devices can do that and where can I get
them ?

Heffron Eli & Sons 139 Hampshire St. in Cambridge MA, phone 617 547-4005 has a bunch of Xerox scanning laser heads (for their laser printers) that has an acoustic-optic modulator that will do what you want. You probably want the video-modulator pizo combo that they are selling for $15 from the head assembly. The idea behind this device is that the acoustic waves in the crystal act as a phase diffraction grating which will divert the beam. The crystal is housed in a metal box with two pinholes.
