开发出一种新型低损耗、单步生长 1.3 µm GaInNAs 可饱和布拉格反射器锁模元件。结合径向厚度和生长后退火控制，可以从一个晶圆上演示 46 nm 的被动锁模调谐范围。通过这种结构，准连续波二极管泵浦 Nd:YLF 和 Nd:YALO 激光器分别在 1314 和 1342 nm 下工作，获得了稳定的锁模，平均接通时间输出功率高达 20 W，脉冲持续时间低至 22 ps。
A novel low-loss, single-step-growth 1.3‐µm GaInNAs saturable Bragg reflector mode-locking element has been developed. Combined radial thickness and postgrowth annealing control have permitted a tuning range of 46 nm for passive mode locking to be demonstrated from one wafer. With this structure, stabilized mode locking was obtained from quasi-cw diode-pumped Nd:YLF and Nd:YALO lasers operating at 1314 and 1342 nm, respectively, with average on-time output powers of as much as 20 W and pulse durations as low as 22 ps.
