| 英文摘要 | PURPOSE:To realize a semiconductor laser light source having a wider varying width of wavelength by setting the optimum wavelength of a nonreflecting coating to be provided on the end face of a single semiconductor laser to shorter wavelength side than the oscillation wavelength of the single laser to be used. CONSTITUTION:A nonreflective coating film 3 is provided on one end face 2 of a semiconductor laser 1, a light emitted from the end face of the film 3 is collimated by a lens 4, reflected by a diffraction grating 5 disposed on an outer optical axis, and returned to the laser A resonator is formed between the grating 5 and the end face 6 not coated with the nonreflective coating of the laser 1, and a laser oscillation is executed. In this case, the optimum wavelength of the coating 3 is set to shorter wavelength side by 40-100nm than the oscillation wavelength (gain peak wavelength) of the sole laser to be used. Thus, the varying width of wavelength of an external mirror type wavelength tunable semiconductor laser light source is increased by shifting the optimum wavelength of the coating 3. |
