Semiconductor laser with a horizontal laser element and a vertical laser element, lidar system and production method

A method for producing a semiconductor laser comprising

• forming a horizontal laser element comprising a first semiconductor layer arrangement having a first active zone for generating radiation,
• wherein forming the horizontal laser element furthermore comprises forming a first optical resonator extending in a direction parallel to a first main surface of the first semiconductor layer arrangement,
• wherein lateral boundaries of the first semiconductor layer arrangement are formed obliquely, such that electromagnetic radiation generated is reflected in the direction of the first main surface of the first semiconductor layer arrangement, and
• the method furthermore comprises forming a vertical laser element comprising a second optical resonator extending in a direction perpendicular to the first main surface of the first semiconductor layer arrangement,
• wherein the vertical laser element is arranged above the first semiconductor layer arrangement on a first portion of the first main surface in a beam path of electromagnetic radiation reflected at one of the lateral boundaries of the first semiconductor layer arrangement,
• the method further comprises forming an output coupling mirror arranged above the first semiconductor layer on a second portion that is different than the first portion and through which the electromagnetic radiation generated is only emitted through the output coupling mirror, and
• the method further comprises forming contact elements for applying a voltage to the horizontal laser element and the vertical laser element.
