| Abstract: | Based on the anisotropic Seebeck effect of oxide high-T c superconductor, a new type laser power meter was designed, and the optical response of this device to the pulsed laser and the chopped laser was measured from infrared to ultraviolet. The measured singnal shows a good linear relation to the laser power in a limited range, and a very fast time response to the irradiating laser. |
