  • Publication number: 20230136630
    Abstract: The optical module disclosed herein has a first lens, a second lens and an array lens arranged sequentially along the main optical axis. 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. A laser beam enters the second lens after passing through the first lens. The second lens diffuses the laser beam along the second direction. 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. The first direction and the second direction are perpendicular to each other.
