Numerical results of rate equations for this four-level system are explained. In experimental part an optical setup is introduced consist of a Ti:Saphhire crystal and two Prism with two mirrors that separated by a beam splitter are used to generate two wavelength tunable laser . 33mJ pulses from a second harmonics of a Q-Switched Nd:YAG laser longitudinally pump the crystal .As output, 5mJ pulses with 10Hz rep rate are measured this is equal to 15% efficiency. By rotating the mirrors the output dual-wavelength pulses adjusted over a wide range 760nm to 810 nm. }, URL = {http://opsi.ir/article-1-293-en.html}, eprint = {http://opsi.ir/article-1-293-en.pdf}, journal = {Accepted and Presented Articles of OPSI Conferences}, doi = {}, year = {2014} }
