18 Channel Modulators
A lot of work has already been done by Drew on the W# modulators. At some other time I will put that information up here.
Since 04/25/2015
I have tested 3 modulators since April 25th. I would upload the videos, but it is taking way to long to do so.
Modulator 1: (Tilted transducers half on and half off the Proton exchanged region).
The red and green channels worked well with intense spots of defracted light. The blue channel was visible but very hard to see. It suffered from heavy attenuation and hardly any blue light made it to the end of the channel. The red laser had 2 modes, TE0 and TE1. The green may have had a 3rd mode but it was very faint. The blue mode lit only 2 modes because of the attenuation.
Modulator 2: (No Channel)
No wavelength worked very well, however the blue light did not attenuate nearly as much in this device. only the second order modes were visible in any color of beam.
Modulator 3: (Transducers completely off of the proton exchanged region. Cracked 4/30/2015 resulting in a short channel.)
The red and green lasers modulated well. Blue has yet to be tested. The intensity matched or exceeded that of M1 at the same voltages. More testing to come.
