| 英文摘要 | The present invention relates to a VCSEL device comprising an optical gain medium (8) arranged between a first DBR (9) and a second DBR (7). The first and the second DBR form a laser cavity and are designed to allow self-contained lasing in the laser cavity,said second DBR (7) being partially transparent for laser radiation resonating in the laser cavity. An optical element is arranged on a side of the second 5 DBR (7) outside of the laser cavity on the optical axis of the laser cavity. The optical element has a concave surface (5) facing the second DBR (7) and being designed to reflect a portion of laser radiation emitted through the second DBR (7) back into the laser cavity. The ratio R/d of the radius of curvature R of the concave surface (5) and the distance d between the concave surface (5) and the gain medium (8) is in the range 10 between 1 and 2. With the proposed VCSEL device a high power output with an improved mode distribution and mode stabilization is achieved. |
