    摘要： In accordance with an aspect of the invention, an apparatus (1) for emitting electromagnetic radiation is provided. The apparatus comprises a gain element (4), an optical arrangement defining a resonator and arranged to re-direct radiation emitted by the gain element (4) along a beam path back onto the gain element (4), the optical arrangement comprising an output coupler (5) configured to couple a portion of the radiation in the resonator out of the resonator, and a pump arrangement configured to pump the gain element. The optical arrangement further comprises a passive device (10), for example a biprism, placed in the resonator in the beam path, the passive device having at least two surface portions (11, 12) at an angle to each other. The passive device (10) is arranged to direct first radiation portions (31) and second radiation portions (32) of the radiation, which first and second radiation portions (31, 32) are incident on different ones of the surface portions (11, 12), to be spatially separated. The apparatus is for example suitable as a source of dual-comb pulsed laser radiation.

    摘要： One aspect of the present disclosure relates to a solid-state laser system, comprising a first at least partially reflective surface; a second at least partially reflective surface, the first and second at least partially reflective surfaces being configured to define opposite ends of a resonant cavity; a solid-state gain material positioned inside the resonant cavity so as to generate at least a primary optical field inside the resonant cavity between the first and second at least partially reflective surfaces; a curved refractive surface positioned inside the resonant cavity so as to cause at least a part of the primary optical field between the first and second at least partially reflective surfaces to propagate through the curved refractive surface.
