Kind Code:
A
Abstract:
To provide a multi-laser device arranged in a head-mounted display.SOLUTION: A multi-laser device includes: a housing 2 including a housing cap 3 and a base plate 4; an opening formed in the housing cap; and a transparent member associated with the opening for passing electromagnetic radiation. A first laser 6 emitting light in a red spectral range, a second laser 7 emitting light in a green spectral range, and a third laser 8 emitting light in a blue spectral range are arranged within the housing. An electrical connection line is routed through the housing to each laser. During operation of the lasers, a majority of the laser's emitted light passes through the transparent member. Each laser is arranged on a pedestal 5 (a) and arranged spaced apart from the lower surface of the base plate (b), and the lasers are aligned with one another (c). The main direction of laser emission is substantially parallel to the base plate of the housing.SELECTED DRAWING: Figure 1
