Abstract
The present application provides an optical module and a medical laser device, belonging to the technical field of applying the light spot, comprising a first lens, a second lens and an array lens arranged in sequence along the main optical axis, wherein the first lens shapes a beam along the first direction of the main optical axis, the second lens shapes the beam along the second direction of the main optical axis, the array of array lenses is arranged along the second direction of the main optical axis. The laser beam enters the second lens after passing through the first lens, and the second lens diffuses the laser beam along the second direction of the main optical axis, and after the laser beam is converted from a Gaussian distribution to a flat-top distribution in the second direction, the laser beam is emitted through the array lens.
