Paper Abstract

The line width of pulse laser is key index to some laser applications. Using finite interferences of high accuracy Fabry- Perot etalon we can measure line width of pulse laser. By this method the line width of a single-longitudinal-mode Nd:YAG laser can be obtained. Reflectance of the etalon used reach 99.8%. The finesse was 300. The accuracy of full width of half height(FWHH) was about 2MHz. It is suitable to measure pulse laser with about 10ns pulse width and 100MHz line width with these parameters.
