Methods and systems may provide for 3D volumetric displays. Such 3D volumetric displays may include a transparent enclosed volume holding a noble gas as a gain medium. Two electrodes positioned on opposing sides of the transparent enclosed volume, may apply a voltage to excite electrons of the gain medium to an excited state. A pump laser may emit a laser beam into the gain medium at a wavelength that has an energy below an absorption line of the gain medium to allow for photon collision while also allowing the laser beam to enter the gain medium. A lens may focus the laser beam to a focused spot within the transparent enclosed volume and move the focused spot as a three-dimensionally scanned voxel to produce a 3D image.
