| 英文摘要 | Provided is a speckle reduction laser that emits laser light by resonating light generated from an active layer (134,240). The speckle reduction laser includes a mode changing unit (150,260) having an electro-optical material layer (155,261) disposed in a resonance path of the laser light, wherein a resonance mode of the laser light is changed when a voltage is applied to the electro-optical material layer (155,261). The last resonator may in addition include a high reflection mirror (120), an AR layer (140) and a partly reflecting mirror (160). The laser active part may be an edge-emitter (130) or a VCSEL. |
