I went to look up regenerative oscillations and but after 10 minutes I still have only a vague understanding of what that even means. My thoughts too... Do they mount the current tech within a vibration-dampening device?My high school physics is seriously failing me here.
One of the problems with mounted sensors and cameras is the vibration that you get when you drive.
Basically, they've tuned the grid, the pumping frequency and the wavelength of the laser cavity so that it goes into harmonic oscillation. By doing this, they can alter the wavelength of the light that comes out the other side of the grating. It's pretty clever.
