Two, three dimensional color displays having uniform dispersion of red, green
and blue visible light emitting micron particles. Pumping at approximately 976
nm can generate green and red colors having an approximately 4% limit efficiency.
One source can generate three colors with approximately limit efficiency. Modulators,
scanners and lens can move and focus laser beams to different pixels forming two
dimensional color images. Displays can be formed from near infrared source beams
that are simultaneously split and modulated with micro electro mechanical systems,
spatial light modulators, liquid crystal displays, digital micromirrors, digital
light projectors, grating light valves, liquid crystal silicon devices, polysilicon
LCDs, electron beam written SLMs, and electrically switchable bragg gratings. Pixels
containing: Yb,Tm:YLF can emit blue light, Yb,Er(NYF) can emit green light, and
Yb,Er:KYF and Yb,Ef:YF3 can emit red light.
