Vertical external cavity surface emitting laser with pump beam reflector |
摘要 |
A vertical external cavity surface emitting laser (VECSEL) using end pumping in which a pumping beam is recycled using a pumping beam reflection layer to increase pumping beam absorption is provided. The VECSEL includes: an active layer for generating and emitting signal light; an external mirror that is separated from and faces a top surface of the active layer and transmits a first portion of the signal light and reflects a second portion of the signal light to the active layer; a first reflection layer contacting a lower surface of the active layer and reflecting the signal light to the external mirror; a pump laser for emitting the pumping beam toward the lower surface of the active layer to excite the active layer; and a second reflection layer contacting the top surface of the active layer and reflecting a portion of the pumping beam back to the active layer.
