Abstract

Holographic television is one of the most exciting as well as challenging developments in the future display market. It allows the reconstruction of a natural-looking 3D scene as all depth cues are provided without the need of any 3D glasses for the viewer [1]. Nowadays, 3D televisions only offer a perception of a 3D image by two 2D images. Hence, the focal plane stays always on the screen while the created 3D image seems to be on another plane. This causes headache to some viewers trying to focus on the 3D object. The holographic display technology overcomes this problem. But the demands on the light sources are very challenging. For large display applications blue, green and red light sources with powers in the Watt range are needed, which have also a spectral linewidth smaller than 5 MHz. Together with the market demands for high efficiencies, direct modulation and small packaging light sources based on diode lasers are most promising.
