Abstract
In various embodiments, an emission source may be provided. The emission source may also include a gain medium including a halide semiconductor material. The emission source may further include a pump source configured to provide energy to the gain medium.
Claims35
An emission source comprising:
- a gain medium that provides optical amplification, the gain medium comprising a three-dimensional halide perovskite material;
- and
- a pump source configured to provide energy to the gain medium comprising the three-dimensional halide perovskite material so that the gain medium generates a coherent stimulated light to emit a laser beam and the gain medium generates amplified spontaneous emission based on the energy provided,
- wherein the three-dimensional halide perovskite material is a halide semiconductor material, and
- wherein the gain medium has a trap density below 1018 cm−3.
