Department of Physics. AMPHOS offers ultrafast lasers with femtosecond to nanosecond pulse durations. The term LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Add Items Retrieve A Fabry-Perot cavity is formed by each spacer layer sandwiched between dielectric stacks. A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other.. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, Nanosecond pulsed fiber lasers, with user-selectable repetition rates, are also based on an all-fiber laser cavity, offering excellent beam quality and wall plug efficiency.
