Study on the spectral narrowing technology of an optically pumped XeF(C-A) laser

The method of the spectral narrowing of optically pumped XeF(C-A) laser is discussed. Two experimental schemes are used to narrow the spectrum of XeF(C-A) laser. Linewidth less than 1 nm can be obtained normally and the minimum linewidth is up to 0.2 nm with more than 2J output energy. Broadband tunability of the XeF(C-A) laser in the spectral range from 448 to 520nm is accomplished. The results of spectral narrowing of XeF(C-A) laser with different experimental schemes are compared and tunable spectra of the XeF(C-A) laser are given.
