摘要

本文从实验和理论两方面对基于体光栅波导的分布式反馈激光器进行了研究和优化。光栅很容易全息地嵌入含有高折射率无机纳米颗粒的染料掺杂有机纳米复合材料层中。结果表明，通过改进波导和光栅的参数，可以获得接近高斯光强分布的窄带激光发射。

Narrow-band DFB laser based on a dye-doped volume Bragg grating

The distributed feedback (DFB) lasers based on a waveguide with volume grating providing feedback through second order Bragg diffraction were experimentally and theoretically investigated and optimized. The gratings are readily inscribed holographically in a layer of a dye-doped organic nanocomposite containing high refractive index inorganic nanoparticles. It is shown that the improvement of the parameters of waveguide and grating provides narrow-band lasing emission with a beam profile close to Gaussian intensity distribution.
