    Oh wow, for a moment there I thought I read "Sumitani"...

    But yeah, technology to make harder, better and stronger displays is nice too.

    uh... i thought the current 532nm green lasers were already, um, green.

    wiki proves me wrong:

    "The green light is generated in an indirect process, beginning with a high-power (typically 100-300 mW) infrared AlGaAs laser diode operating at 808 nm. The 808 nm light pumps a crystal of neodymium-doped yttrium aluminum vanadate (Nd:YVO4) (or Nd:YAG or less common Nd:YLF), which lases deeper in the infrared at 1064 nm. The vanadate crystal is coated on the diode side with a dielectric mirror that reflects at 1064 nm and transmits at 808 nm. The crystal is mounted on a copper block, acting as a heatsink; its 1064 nm output is fed into a crystal of potassium titanyl phosphate (KTP), mounted on a heatsink in the laser cavity resonator. The orientation of the crystals must be matched, as they are both anisotropic and the Nd:YVO4 outputs polarized light. This unit acts as a frequency doubler, and halves the wavelength to the desired 532 nm."

    thanks for clearing that up, wiki.

    @BullLifter: Interestingly enough, one of the things that I always thought was odd was this:
    Luke's lightsaber = Green
    Darth Vader's lightsaber = Red
    TIE fighter cannon fire = Green
    X-Wing cannon fire = Red

    Always wondered why they did it that way.

    Approve, I do, but much to learn, you have.

    As if I didn't need another reason to wait to buy my HDTV.

    @Ali Khan: I barely watch enough TV to justify having an HDTV. If I get one, it'll probably be some modest sized thing just large enough to comfortably watch from across the room.
