  In this review, we have presented recent high-resolution photoemission results by using the ultra-violet laser as an excitation source. Due to the narrow band width of the light source and the improvement of the detection system, the overall instrumental resolution was improved up to 0.35 meV. Low energy excitation allows us obtaining the more bulk-sensitive measurements than the conventional high-resolution photoemission spectroscopy. These advantages appeared on some recent results on superconductors (Nb and Mg(B<sub>1-x</sub>C<sub>x</sub>)<sub>2</sub>) and other correlated materials (FeSi and LiV<sub>2</sub>O<sub>4</sub>). Angle-resolved photoemission of Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>8+δ</sub> shows very sharp spectra, which allows us to discuss much more intrinsic electronic structure. These results demonstrate the promising future of the high-resolution and low energy excitation photoemission spectroscopy.<br>
