摘要： The invention concerning a pulsed laser is provided and includes an optical resonator being defined by at least two reflective elements, and the optical resonator defining a laser radiation beam path; the laser further including a solid-state gain structure arranged so as to be in the beam path, the gain structure being operable to emit laser radiation by stimulated emission upon being pumped; a housing operable of maintaining a vacuum or gas composition different from ambient gas within the housing, the housing defining an inside, which encloses at least a part of the optical resonator, so that at least a part of the beam path proceeds within the housing; and a mode locker arranged so as to be in the beam path; wherein the gas composition and/or gas pressure in the housing is controlled, and a gas mixture inside the housing has an optical nonlinearity which is lower than the nonlinearity of air.
