摘要

设计并制造了高性能 808 纳米五结垂直腔面发射激光器（VCSEL）。比较了 808 纳米五结 VCSEL 和单结 VCSEL 的光-电流-电压特性。808 纳米五结 VCSEL 在 5~^{\circ }$ C 时的斜率效率高达 5.92 W/A，在 25~^{\circ }$ C 时的斜率效率高达 5.10 W/A。808 纳米五结独立 VCSEL 的最大功率转换效率为 55.04%。在短脉冲条件下（400 Hz，60 ns 脉宽），五结 VCSEL 阵列在 224 A 时的峰值输出功率为 1.013 kW。这种具有高功率密度的多结 808 nm VCSEL 在 Q 调谐固体激光器中具有重要的应用价值。

High Power Multi-Junction 808 nm Vertical Cavity Surface Emitting Lasers With High Efficiency

High-performance 808-nm five-junction vertical cavity surface emitting lasers (VCSELs) are designed and fabricated. The light-current-voltage characteristics of the 808-nm five-junction and single-junction VCSELs are compared. The 808-nm five-junction VCSELs with a high slope efficiency of 5.92 W/A at

$5~^{\circ }$

C and 5.10 W/A at

$25~^{\circ }$

C are achieved. The maximum power conversion efficiency is 55.04% for the 808-nm five-junction individual VCSEL. Under short pulse conditions (400 Hz, 60 ns pulse width), the peak output power of the five-junction VCSELs array is 1.013 kW at 224 A. Such multi-junction 808 nm VCSELs with a high power density have important applications in Q-tuned solid-state lasers.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
