光抽运垂直外腔面发射半导体激光器(VECSELs)综合了传统面发射半导体激光器和光抽运固体激光器的优点,既能获得近衍射极限的圆形TEM00模,又能产生数瓦量级甚至更高的功率,实现了高光束质量和高输出功率的完美统一。此外,垂直外腔面发射半导体激光器可利用成熟的量子阱能带工程
Optical pumping Vertical external cavity surface emitting semiconductor lasers (VECSELs) combine the advantages of conventional surface-emitting semiconductor lasers and optical pumping solid-state lasers to achieve near-diffraction-limited circular TEM00 modes and to produce orders of magnitude higher or even higher Of the power to achieve a perfect unity of high beam quality and high output power. In addition, vertical-cavity-surface-emitting semiconductor lasers can harness sophisticated quantum well band-to-band engineering
