| Research Abstract |
I have constructed commercially available laser photoemission system and achieved 370 ueV of energy resolution that enables us to measure superconducting gap of niobium and V3Si. It is first time to realize the energy resolution better than 1meV using commercially available laser. 180 ueV of energy resolution is easily realized using this system. Additionally, I have succeeded to observe the superconducting gap of k-(BEDT -TTF)_2Cu(NCS)_2 for the first time in the world.
