Paper Abstract

The laser properties of the Rhodamine B and Rhodamine 6G doped xerogels as the solid dye tunable laser active materials are studied. The second harmonic wave 532 nm of Q- switched Nd:YAG laser with 22 ns pulse width was used as the pumping laser. With 0.2 mJ - 0.7 mJ pulse energy of pumping laser we obtained the output laser pulse with some (mu) J. The measured center wavelength for Rhodamine B is 594 nm, the spectral range is 585 nm - 604 nm, the energy conversion efficiency is 25%. For Rhodamine 6G the center wavelength is 566 nm, the spectral range is 556 nm - 575 nm, the energy conversion efficiency is 35%.
