ABSTRACT
Two-lens slit filtering has great prospects for high-power lasers due to the excellent properties of inhibition of pinhole closure and compactness of the laser facility. With analysis of the beam profile, power spectrum density and near-field parameters, two-lens slit filtering and its image relay characteristic are experimentally demonstrated, showing a great improvement in beam quality and a good image relay property.
