Laser Cavity

Silicon fluorescent nanoparticles when aggregated make crystals. The microscopic cavity was designed by coating the crystal with an acrylic gel. The thin acrylic shell is the cavity. When hit with a green light in the 560 nm range, the cavities fluoresce in the red at 620 nm. Note the beam.
