Semiconductor laser element

Abstract

This semiconductor laser element comprises an element body that emits laser light from a first end face. The element body has a first recessed portion located between a first side face and an element front face, recessed towards the interior of the element body, and a second recessed portion located between a second side face and the element front face, also recessed towards the interior of the element body. The first recessed portion has a first inner surface oriented towards the first side face and a first connecting surface that joins the first inner surface and the first side face. The second recessed portion has a second inner surface oriented in the same direction as the second side face and a second connecting surface that joins the second inner surface and the second side face.The first connecting surface and the second connecting surface each have an inclined surface which is inclined at an angle to the first element surface that differs from that of the first side surface and that of the second side surface.
