激光的半经典描述被用来计算由于激光腔内的吸收介质的小扰动而引起的激光强度的变化。假设激光器在其振荡阈值附近以单模工作。本文导出了激光腔内吸收测量相对于常规吸收测量的探测灵敏度提高的表达式，并给出了探测灵敏度的估计。
A semiclassical description of the laser is employed to calculate the change in laser intensity due to the small perturbation of an absorbing medium within the laser cavity. The laser is assumed to be operating in a single-mode near its threshold of oscillation. An expression is derived for the enhancement in detection sensitivity of laser intracavity absorption measurements over conventional absorption measurements and estimates of detection sensitivity are given.
