| 摘要 |
The present invention relates to a device for generating a single polarization optical fiber laser, which generates a laser beam, capable of: enabling self-starting using a polarization maintaining optical fiber; being strong to a change of an outer environment; minimize increase of a device volume by controlling dispersion inside; controlling a pulse width of the laser beam inside with time sustainability in a femtosecond unit; and maintaining a single polarization state. According to the present invention, the device for generating a single polarization optical fiber laser includes: an optical path unit including the polarization maintaining optical fiber and providing a moving path of the laser beam; a pump light supply unit supplying pump light to the optical path unit; a laser medium unit arranged on the moving path and outputting the laser beam to the optical path unit by generating a density reversal phenomenon of the pump light; a pulse width control unit arranged on the moving path and controlling and outputting the pulse width of the output of the laser medium unit; a dispersion compensation unit compensating and outputting the dispersion of the pulse width control unit and arranged on the moving path; and an output unit outputting at least a part of the output of the dispersion compensation unit and arranged on the moving path. |
