四棱镜扩束染料激光器的多线振荡

Multiline oscillation of pulsed dye laser with four-prism expander

从实验和机理上研究了四棱镜扩束染料激光器产生的多线振荡,结果表明:其振荡线间隔、单线线宽、多线带宽是与多界面反射器-光栅复合腔对光束的频率和空间调制特性相符合的.

Multiline osciilation of the dye laser with four prisms and a grating has been observed and studied. The results are shown that the output spectral features, such as wavelength interval of the neighboring lines, distributive bandwidth of the multiline and singlet width, are in agreement with the theory of compound cavity with multisurface reflector and grating combination.
