光阱内泵浦被证明可以导致半导体盘激光器使用谐振吸收或使用外部光学的高效操作。对于发射约980 nm的激光，在940 nm处的泵浦辐射吸收为70%。激光输出功率为1.9 W，斜率效率高达35%，基于入射功率。
Optical in-well pumping is shown to lead to highly efficient operation of semiconductor disk-lasers using resonant absorption or using external optics. Pump radiation absorption of 70% at 940 nm is demonstrated for a laser emitting around 980 nm. Laser output power was 1.9 W with slope efficiencies up to 35% based on the incident power.
