Description
Description
Optoelectronic module and process for the manufacture thereof Technical Field
[0001] The invention relates to the product and process as per the first portion of the independent claims.
Background Art
[0002] By laser diode (LD), injection laser diode (ILD), or diode laser is meant any semiconductor device in which a light-emitting diode pumped directly with electrical current creates lasing conditions at its junction. NPL1 provides a comprehensive treatment of these and other photonic integrated circuits.
[0003] Diode array modules are commonly employed in laser light shows, that is, visual displays wherein substantially collimated beams of coherent light generated by one or more laser sources are projected aerially or scanned in two dimensions, usually with oscillating mirrors, to produce visible images on a projection surface. Differing substantially from conventional cinema and video area-filling displays, laser-light show images typically consist of high-contrast outline renderings and silhouettes. Images are produced by a vector graphics scanning method and retain the distinguishing properties of coherent laser light, namely its collimation, monochromaticity, or pure hue(s), and its fine interference patterns, or speckle. PTL1 discloses such method.
Summary of invention
[0004] The invention is set out in the appended set of claims.
Technical Problem
[0005] In display and other high-power laser systems, white light is produced by superimposing individual color channels such as red, green, and blue. This superposition is effected by beam combiners based on mirrors or dichroic filters in small holders that, when being transported, tend to misalign. Furthermore, heat dissipation causes nonuniform expansion or contraction of integral or connected components. These and other adverse effects are laid out in NPL2 and, if color fringing is to be avoided, necessitate realignment of optical components prior to each use.
Solution to Problem
[0006] The problem is solved as per the second portion of Claim 1.
Advantageous effect of invention
[0007] The invention provides for an essentially maintenance-free optoelectronic module. In a preferred embodiment, the module will resist misalignment across a temperature range of -36 °C to +110 °C.

Description of embodiments
[0026] Figure 1 illustrates a module (10) for linear combination of five laser beams through knife edging. Here, each of the five small mirrors (11) used for knife-edge adjustment is installed on a rectangular pedestal (14) arrayed on a cascaded mounting surface (13). Partly obscured below each pedestal (14), a recess (15) is filled with an adhesive such that the corresponding mirror (11) is firmly joined on the surface (13) through the adhesive and pedestal (14). In the present embodiment, a thixotropic two-component (11 , 12) adhesive based on polyurethane resin is
employed.
[0027] Figure 2 shows a beam combiner module (10) based on dichroic filters (12), sometimes referred to as dichroic mirrors, dispersed across a common baseboard (16). Seven troughs (17) consisting of a suitable aluminum alloy - as are elucidated in further detail in Figure 3 et segg. - are affixed on the baseboard (16), with each trough (17) being connected to the baseboard (16) by an M3 screw (21) and bearing a cube (18) on its front rim.
[0028] By way of example, the cube (18) depicted in the bottom left corner of Figure 2 serves as a kinematic mount for a small mirror holder (19), its three setscrews (20) accessible from the side facing the viewer. Upon precise factory setting by means of these setscrews (20) - resulting in the configuration shown -, the trough (17) may be filled with adhesive until the head of the screw (21 ) is fully embedded and the holder (19), cube (18), and filter (12) are partly immersed. Once the adhesive has fully cured, the filter (12) will be permanently fixated relative to the baseboard (16) and the screw (21) prevented from loosening.
Industrial applicability
[0029] The invention is applicable, among others, throughout the entertainment industry.
