Laserit

Laserit is a fictional crystalline material developed in speculative science and science fiction as a versatile lasing medium. The name combines laser with the common mineral suffix -it, signaling its role as a primary component in laser systems within imagined worlds. In literature and theoretical discussions, Laserit is depicted as possessing high optical gain, broad tunability across the visible and near-infrared spectrum, and exceptional thermal stability, enabling continuous-wave and pulsed operation under demanding conditions.

Materials described as Laserit are often said to have a transparent, defect-tolerant lattice and low non-radiative losses. Some depictions assign it a high refractive index and strong mechanical robustness, while others emphasize radiative efficiency achieved through specialized dopants or crystal symmetry.

In fictional settings, Laserit is sourced from rare mineral deposits on asteroids or mined from exotic planetary crusts, or synthesized in advanced laboratories using high-temperature, high-pressure processes. Its production is usually costly and tightly regulated due to its value for coherent light generation.

Applications within stories range from compact, high-brightness lasers used in communications and medical devices to precision sensing and directed-energy systems. The flexible emission characteristics allow authors to explore ideas about beam quality, efficiency, and material science.

Because Laserit is a fictional construct, its properties vary by author and context. It serves as a conceptual tool to illustrate challenges and opportunities in lasing media, materials science, and photonics research.
