Semiconductor laser component and method for operating at least one semiconductor laser

A semiconductor laser component comprising:

• a plurality of semiconductor lasers, each of the semiconductor lasers configured to emit primary electromagnetic radiation of a primary spectral bandwidth in a visible wavelength range;
• and
• a beam combiner configured to:
• combine the primary electromagnetic radiations emitted from the semiconductor lasers,
• form secondary electromagnetic radiation from a superposition of the primary electromagnetic radiations of the semiconductor lasers, and
• couple the secondary electromagnetic radiation out from the beam combiner,
• wherein the secondary electromagnetic radiation has a secondary spectral bandwidth that is at least twice as large as an average value of the primary spectral bandwidths;
• and
• an optical layer sequence arranged within a resonator of at least one semiconductor laser, a refractive index of the optical layer sequence being variable by applying an external electric voltage or electric current.
