Claim 35:
36. A multi-laser arrangement, in particular an RGB laser module, comprising:
a housing including:
a housing cap having at least one opening formed therein, and a transparent element associated therewith for passing electromagnetic radiation; and
a base plate;

a first laser emitting light in the red spectral range of the visible spectrum;
a second laser emitting light in the green spectral range of the visible spectrum;
a third laser emitting in light in the blue spectral range of the visible spectrum, the first, second and third lasers being arranged within the housing;
an electrical connection line routed through the housing to each respective laser; and
wherein, during operation of the lasers, a majority of the laser's emitted light passes through the transparent element;
wherein each laser
(i) is arranged on a pedestal in the housing;
(ii) is arranged spaced apart from the lower surface of the base plate; and
(iii) is aligned with one another;, wherein a main direction of laser emission is substantially parallel to the base plate of the housing,, wherein the base plate has a ratio V of L to W (V=L/W),
from 2 to 4.5, preferably from 3.4 to 4 when the transparent element is arranged perpendicular relative to the base plate; and
from 4 to 20, preferably from 6.6 to 13.5, when the transparent element is arranged with an inclination relative to the base plate;
wherein L is the distance from a front side of the pedestal in a main emission direction of the lasers to an edge of the base plate located in the main emission direction of the lasers; and
wherein W is a thickness of the base plate along the distance L.
