Abstract
A semiconductor emitter (1; 12; 14; 18; 21; 23; 25; 27; 30; 32; 34), comprising an amplifier medium (2) and at least one waveguide (3, 4) arranged at the amplifier medium (2), wherein at least one light coupling-out region (10; 13; 15; 19; 20; 22; 24; 26a-e; 33; 35) is present at at least one waveguide (3), and at least one wavelength-converting phosphor (11; 28; 31r, 31g, 31b) is disposed downstream of at least one coupling-out region (10; 13; 15; 19, 20; 22; 24; 26a-e; 33; 35).
Claims12
A semiconductor emitter, comprising an amplifier medium and at least one waveguide arranged at the amplifier medium, wherein
- at least one light coupling-out region is present at at least one waveguide, and
- at least one wavelength-converting phosphor is disposed downstream of at least one coupling-out region.
A method for generating useful light from laser light, wherein the useful light is coupled out from at least one waveguide arranged at an amplifier medium for generating the laser light.
