Abstract
A laser emitting apparatus includes an incoherent light-emitting device having a light-emitting layer wherein an electric field is applied across the light-emitting layer to produce light which is transmitted out of the incoherent light-emitting device and a vertical laser cavity structure disposed to receive light transmitted from the incoherent light-emitting device and produce laser light.
Claims12
A laser emitting apparatus, comprising:
- a) an incoherent light-emitting device having a light-emitting layer and a means for applying an electric field across the light-emitting layer to produce light which is transmitted out of the incoherent light-emitting device;
- b) a vertical laser cavity structure disposed to receive a pump beam light transmitted from the incoherent light-emitting device, such structure including:
- i) first means for receiving light from the incoherent light-emitting device and being mainly transmissive or reflective over predetermined ranges of wavelengths;
- ii) an organic active layer for receiving light from the incoherent light-emitting device and from the first light-receiving means and for producing laser light;
- and
- iii) second means for reflecting light from the organic active layer back into the organic active layer, wherein a combination of the two means transmits the laser light.
