德国研究者研制一种量子点激光器,其准连续波输出为11.7W,一般连续波输出的最大功率为4.7W。 这是迄今量子点激光器报道的最高输出功率,其中之一首次超过10W。 柏林理工大学的DieterBimberg及其同事制成此种器件,它由6层量子点重重堆叠,形成增益介质。 此激光器基于镓砷波导和铟镓砷点,在1135nm处发射,将其输出设定为1.5W,其室温寿命超过
German researchers to develop a quantum dot laser, the quasi-continuous wave output of 11.7W, the general continuous wave output of the maximum power of 4.7W. This is by far the highest output power reported by quantum dot lasers, one of which exceeded 10W for the first time. DieterBimberg of Berlin Polytechnic University and colleagues made the device, which consists of six layers of quantum dots stacked together to form a gain medium. Based on gallium arsenic waveguides and indium gallium arsenic spots, this laser emits at 1135 nm, sets its output to 1.5 W, and its lifetime at room temperature exceeds
