Patent ID: 7561610

Claim:
A semiconductor laser apparatus comprising: a first semiconductor laser device that has a first electrode and a second electrode and emits a light beam having a first wavelength; a second semiconductor laser device that has a first electrode and a second electrode and emits a light beam having a second wavelength longer than said first wavelength; and a conductive package that houses said first and said second semiconductor laser devices; first and second power supply pins provided in said package; and a submount made of an insulator on which said first semiconductor laser device and said second semiconductor laser device are arranged, wherein said first and second power supply pins are electrically isolated from said package, wherein said first electrode and said second electrode of said first semiconductor laser device are electrically connected to said first and second power supply pins, respectively, and simultaneously electrically isolated from said package by said submount, and said first electrode or said second electrode of said second semiconductor laser device is electrically connected to said package.
