Multi-source laser head for laser engraving

A system, comprising:

• a first laser source that generates a first laser beam and is optically coupled to a first optical fiber that transmits the first laser beam;
• a second laser source that generates a second laser beam and is optically coupled to a second optical fiber that transmits the second laser beam;
• and
• an optical device that includes:
• a first connector for the first optical fiber;
• a second connector for the second optical fiber;
• and
• one or more optical elements that direct the first laser beam from the first connector to a first beam collimator and direct the second laser beam from the second connector to the first beam collimator,
• wherein, the first beam collimator:
• produces a first collimated beam based on the first laser beam,
• directs the first collimated beam to a laser-scanning device, produces a second collimated beam based on the second laser beam, and
• directs the second collimated beam to the laser-scanning device.
