Laser module and laser processing machine

A laser module comprising:

• a first substrate;
• a first laser light source that is provided on a first plane of the first substrate and emits first light in a first direction that is a perpendicular direction of the first plane;
• a second laser light source that is provided on the first plane and emits second light in the first direction;
• a first mirror that reflects the first light emitted from the first laser light source in the first direction;
• a second mirror that transmits the first light reflected by the first mirror in a second direction different from the first direction and reflects the second light emitted from the second laser light source in the second direction;
• a first condensing optical system that is provided between the first laser light source and the first mirror, and
• a second condensing optical system that is provided between the second laser light source and the second mirror,
• wherein a radiation angle of the first light emitted from the first laser light source is the same as a radiation angle of the second light emitted from the second laser light source,
• a distance between the first laser light source and a principal point of the first condensing optical system is greater than a distance between the second laser light source and a principal point of the second condensing optical system,
• an optical path length from the first laser light source to the second mirror is greater than an optical path length from the second laser light source to the second mirror, and
• a focal length of the first condensing optical system is greater than a focal length of the second condensing optical system.
