| 英文摘要 | PURPOSE:To make the wavelength difference between a low power reading beam and a high power writing beam small by a method wherein a first light emitting region of a coating film deposited on a rear end face and a second light emitting region of a coating film deposited on a front and a rear end face are provided. CONSTITUTION:A light emitting front end face 1 of a laser diode A and a light emitting front end face 2 of a laser diode B are formed. A resonator front end face coating film 13 of the laser diode A whose reflectivity is 1-4%, a resonator front end face coating film 14 of laser diode B whose reflectivity is 25-33%, a resonator rear end face coating film 15 of the laser diode A whose reflectivity is 50-65%, and a resonator rear end face coating film 10 of the laser diode B whose reflectivity is 25-33% are formed. By this setup, the injection currents of the laser diodes A and B are separated from each other. As mentioned above, a laser device of this design is so constituted as to be provided with light emitting regions, whereby the wavelength difference between the optical outputs of a first and a second light emitting region set to 18-20mW and 2-4mW required for a writing and a reading light source respectively can be made small to be 2nm or less. |
