Abstract
In at least one embodiment, the bar laser () has a semiconductor layer sequence () with an active zone (). A waveguide () with a defined width (B) is formed as an elevation from the semiconductor layer sequence (). A contact metallization () is applied to an upper side () of the waveguide () facing away from the active zone (). A current flow layer () is in direct contact with the contact metallization (). The contact metallization () is electrically connected via the current flow layer (). A current flow width (C) of the active zone () and/or the waveguide () is less than the width (B) of the waveguide ().
