Laser-machined GaP monolithic displays
Applied Physics Letters, 1974The feasibility of producing electrically and optically isolated monolithic devices from planar GaP p-n junction material by the use of laser-machining techniques has been demonstrated. By machining deep narrow grooves through the p-n junction and around the areas to be contacted, it is possible to produce monolithic displays without the use of ...

Safety Aspects of Laser Displays
Radiation Protection Dosimetry, 1997Lasers have been used for entertainment almost since their first practical operation reported in 1960. Laser displays started in 1973. There is no doubt that the uses of lasers for entertainment are impressive. However, there are a number of safety issues. Laser displays consist of two types of visual effects: beams and graphical images.

Color speckle in laser displays
SPIE Proceedings, 2015At the beginning of this century, lighting technology has been shifted from discharge lamps, fluorescent lamps and electric bulbs to solid-state lighting. Current solid-state lighting is based on the light emitting diodes (LED) technology, but the laser lighting technology is developing rapidly, such as, laser cinema projectors, laser TVs, laser head ...
