摘要

本文提出了一种利用一维光栅作为太赫兹激光器的输出耦合器来测定一维光栅损耗的实验方法。首先，我们通过实验确定了介质衬底上两种光栅的最佳耦合系数:线栅和条栅。因此，我们确定了每个光栅在激光腔内的总损耗值。比较这些结果，可以确定由特定光栅引起的损耗。

A method of loss determination in 1D gratings in the THz range

In this paper we present an experimental method of determining losses caused by 1D gratings based on applying those gratings as output couplers of THz lazers. Firstly we experimentally determined the optimal coupling coefficient for two types of gratings: wire gratings and strip gratings on dielectric substrates. Therefore we determined the value of total losses in laser cavity for each researched grating. Comparing these results it is possible to determine the losses caused by specific grating.
