Unfortunately, the flicker is essential for the excellent motion quality CRTs are renowned for. If the image on the screen stays constant while you eyes are moving, the image formed on your retina is blurred. Blurbusters has a good explanation:
CRT phosphors light up extremely brightly when the electron beam hits them, then exponentially decay. Non-phosphor-based display technologies can attempt to emulate this by strobing a backlight or lighting the pixel for only a fraction of the frame time, but none can match this exponential decay characteristic of a genuine phosphor. I'd argue that the phosphor decay is the most important aspect of the CRT look, more so than any static image quality artifacts.
There is such a thing as a laser-powered phosphor display, which uses moving mirrors to scan lasers over the phosphors instead of an electron beam, but AFAIK this is only available as modules intended for building large outdoor displays:
