Beam shaping assembly and laser device

The invention discloses a light beam shaping assembly and a laser device, and relates to the technical field of laser, the light beam shaping assembly comprises a first aspheric lens, a spherical lens and a second aspheric lens which are sequentially arranged in the optical axis direction, and a Gaussian beam is converged and homogenized through the first aspheric lens and then diverged through the spherical lens to form a Gaussian beam. And finally, the light is collimated and homogenized by the second aspheric lens and is emitted to form a flat-topped light beam. According to the light beam shaping assembly and the laser device provided by the invention, collimation and homogenization of high-power laser can be realized within the preset working distance. 本申请公开了一种光束整形组件及激光装置，涉及激光技术领域，本申请的光束整形组件，包括沿光轴方向依次设置的第一非球面透镜、球面透镜和第二非球面透镜，高斯光束经过第一非球面透镜的会聚和匀化，再经过球面透镜的发散，最后经过第二非球面透镜的准直和匀化出射形成平顶光束。本申请提供的光束整形组件及激光装置，能够在预设工作距离内实现大功率激光的准直和匀化。
