laserteho

Laserteho is a metric used in photonics to quantify the overall effectiveness of a laser system, combining nominal output power, beam quality, pulse structure, spectral properties, and system losses into a single figure of merit. It is not a formal unit but a comparative tool.

The metric is typically defined as L = (P_out / P_in) × B × S, where P_out is useful optical power delivered to the target, P_in is electrical input power, B is a beam-quality factor derived from M^2 and mode structure, and S is a pulse/spectral factor capturing whether the laser is continuous or pulsed, and spectral purity. The exact form varies by organization.

Measurements require calibrated power meters, beam-profile analyzers, and spectrometers. Because laserteho is not yet standardized, practitioners customize the factors and ensure clear documentation when comparing systems.

Used in industry and research to compare laser platforms for manufacturing, materials processing, medical devices, and defense. It facilitates cross-wavelength comparisons but can be sensitive to definition choices; not universal.

The term has appeared in recent photonics literature as a practical, non-standard metric for system-level performance.
