PURPOSE:To output high power laser light accurately by injecting and synchronizing laser light which is obtained from a single-mode laser through a polarization splitting optical system and anamorphic prisms, polarizing and splitting the laser light emitted from a broad area laser, and taking out the output laser light. CONSTITUTION:First taking light L10 obtained from a single-mode laser 3 is injected and synchronized in a broad area laser 1 through a polarization splitting optical system comprising units 12, 5 and 13 and anamorphic prisms 14. Second laser light L20 emitted from the broad area laser 1 is polarized and split in the poralization splitting optical system comprising the units 13, 5 and 12 through the anamorphic prisms 14, and output laser light L21 is taken out. In this way, the high power, coherent laser light L21 in a single mode can be outputted accurately. |
