By using Nd:GdVO 4 as the gain medium and the Raman medium simultaneously, the actively Q-switched operation of the self-Raman Nd:GdVO 4 laser at 1173nm was realized. The output characteristics versus the incident pump power and the pulse repetition rates were investigated. At a pulse repetition rate of 30kHz an average power up to 1.22W was obtained with the incident pump power of...
The radiation transfer equations of the extracavity Raman laser including up to the third Stokes beams and backward Raman scattering terms were deduced in detail from the wave equation and material equations of stimulated Raman scattering. The radiation transfer equations were solved numerically to optimize the performance of the extracavity Raman lasers with barium nitrate crystal as the nonlinear...
