摘要
We compare the stimulated Raman scattering(SRS)performance of a-cut and c-cut YVO4 in a single-pass Raman experiment.The undoped YVO4 crystal shows its good SRS capability in a quasi-transient field.The non-axial scattering angles of Raman radiation are also studied,and the result is in good agreement with the physical model based on the phase matching condition.High-order Raman Stokes and anti-Stokes lights with good beam quality are obtained by means of Raman amplification.Our experiments show that Raman amplification is a practical way to avoid unexpected nonlinear effects and to obtain new wavelength picosecond lasers.
