Laser system with monolithic optical collimation and circularisation device

Abstract

The invention relates to a laser system (1) comprising a solid amplifying medium (2) capable of emitting an amplified beam (4) in a propagation direction (D), the amplified beam having a first angle of divergence in a first plane (Px) including the propagation direction, and a second angle of divergence in a second plane including the propagation direction and separate from the first plane, the second angle of divergence being separate from the first angle of divergence; and an optical device (3). According to the invention, the optical device comprises a lens (31) arranged so as to refract the amplified beam into an outgoing beam (5), the lens having a first radius of curvature in the first plane and a second radius of curvature in the second plane, the second radius of curvature being separate from the first radius of curvature.
