Laserin
Laserin is a term used in theoretical and speculative discussions to denote a class of compact, high‑efficiency laser sources that aim to combine broad tunability with excellent beam quality. In proposed models, Laserin devices are envisioned as solid-state or semiconductor lasers integrated with microcavity resonators, enabling direct emission across a wide spectral range through diode pumping and intracavity nonlinear processes within the cavity. The concept draws on advances in microcavity lasers, photonic crystals, and integrated nonlinear optics.
Key design ideas include strong optical confinement in a low‑loss resonator, suppression of multi‑mode operation to
Reported performance targets in speculative work include high slope efficiency, low threshold operation, narrow spectral linewidths,
