A laser arrangement includes an optical resonator having a V arrangement of two resonator branches. At least one active medium includes an active volume associated with each resonator branch. The arrangement also includes folding element that is highly reflective for a fundamental wavelength of the laser arrangement and an optical pump imaging system configured to unidirectionally pump the two resonator branches. The optical pump imaging system includes a common objective lens for both resonator branches. The folding element is transparent for the pump wavelength.
