Abstract

The laser module includes a QCL element and a support member. The QCL element has a first end surface located on a first side in a second direction orthogonal to a stacking direction and a second end surface located on a second side opposite to the first side in the second direction. The substrate has first to fourth substrate-surfaces. The support member has a first portion having a first surface facing at least a portion of the fourth substrate-surface, and a second portion having a second surface facing at least a portion of the first substrate-surface and a third surface located opposite to the second surface in the second direction. At least a part of the terahertz wave generated in the active layer is incident on the second surface of the support member through the substrate and is emitted from the third surface through the inside of the second portion.
