Laser is a device that emits coherent monochromatic beam of light through an optical amplification process based on stimulated emissions of the electromagnetic radiations. Lasers are employed in the processing of disparate materials in engineering and manufacturing of electronic components. Laser materials are used in instrumentation, communication, lithography, printing, and displays. Laser technology is utilized in different verticals including medical, semiconductor, electronics, aerospace & defense.
A phosphor is a substance that emits light upon exposure of an electron beam or ultraviolet radiation. Phosphors are useful materials in the manufacture of LEDs. The chemistry and composition of phosphor largely determine the light quality, stability and efficiency of an LED. The LED technology is widely being used in illumination applications in automotive and households. LED bulbs consume lesser energy while producing a light having intensity higher than that of incandescent bulbs. Also, LED lights last longer than CFLs and even surpass them in terms of energy efficiency.
