The CRTs used in the Sinclair TV80, and in many Sony Watchmans were flat in that they were not deep and their front screens were flat, but their electron guns were put to a side of the screen. [ 490 ] [ 491 ] The TV80 used electrostatic deflection [ 492 ] while the Watchman used magnetic deflection with a phosphor screen that was curved inwards.
Green laser pointers [192] appeared on the market circa 2000, and are the most common type of DPSS lasers (also called DPSSFD for "diode pumped solid state frequency-doubled"). In late 2004 and early 2005, came a significant increase in reported incidents linked to laser pointers – see Lasers and aviation safety. The wave of incidents may ...
