Single-frequency monolithic linear laser device and system comprising same

The invention relates to laser device comprises: Suitable generating a fundamental wavelength laser beam (13) and medium (1 and 7); For time is a to generate the harmonic wavelength laser beam (14) and refraction misalignment medium a fundamental wavelength laser beam (3, 20 and 20); For choosing the fundamental wavelength laser beam polarization's polarization medium (1b, 5, 6, 2, 8, 9, 16 and 20); the polar medium requirement and connected with the input the fundamental wavelength wherein the output aspect's a fundamental. The invention the polar medium (1b, 5, 6, 2, 8, 9, 16 and 20) comprises the is vertical to the separating to the polar medium the fundamental wave output surface (2b). Magnified medium and a spot misalignment medium handle, and forming a monolith resonant cavity.
