Efficient end-pumped slab Nd:YVO4 laser with a multifolded quasi-concentric resonator

Solid State and Liquid Lasers


A novel end-pumped slab Nd:YVO4 laser with a multifolded quasi-concentric resonator (FCR) is reported. This planar-folded stable resonator matches the sheet-shaped pump volume with the TEM00 mode and yields highly efficiently laser operation with a good beam quality. In a prototype experiment, a 19.55-W output was achieved with a pump power of 45 W, which was single mode in one direction. In addition, the optical-to-optical efficiency reached 43.4%. After introducing a telescope system into the folding plane, a 10.23-W quasi-TEM00 output was obtained, and the overall efficiency was 22.7%.
