Laser package and method for operating a laser package

A laser package comprising:

• at least a first laser diode set having at least two laser diodes emitting light beams of a first color,
• at least a second laser diode set having at least two laser diodes emitting light beams of a second color, and
• a beam combiner comprising a plate having a selectively reflective front surface and an at least selectively reflective back surface,
• wherein a first light beam and a second light beam transmitted from the at least two laser diodes of the first laser diode set have different polarizations,
• wherein a first light beam and a second light beam transmitted from the at least two laser diodes of the second laser diode set have different polarizations,
• wherein the selectively reflective front surface of the plate is configured to reflect the first light beam emitted by first laser diode set as well as the first light beam emitted by the second laser diode set, and to transmit the second light beam emitted by first laser diode set as well as the second light beam emitted by the second laser diode set,
• wherein the selectively reflective back surface of the plate is configured to reflect the second light beam emitted by first laser diode set as well as the second light beam emitted by the second laser diode set,
• wherein the second light beam emitted by first laser diode and reflected by the selectively reflective back surface of the plate as well as the second light beam emitted by second laser diode and reflected by the selectively reflective back surface of the plate pass through the selectively reflective front surface of the plate, and
• wherein the plate is configured to have a distance between the selectively reflective front surface and the selectively reflective back surface that is set so that beam centers of the first and second light beams of the first and second laser diode set reflected by the plate overlap.
