注入锁定是利用注入锁定来缩小主动锁模激光二极管（ML-LD）各个模式的谱线宽度。注入锁定ML-LD的多模分布在3.0 THz以上，下行30 dB时间距为25 ghz；线宽和稳定性（~ 25mhz）与主激光器基本相同。我们还演示了使用注入锁定ML-LD稳定到分子(H(13)C (15)N,(13)C（2)H(2)）吸收谱线的激光二极管的精确频率测量。
Injection locking is employed to narrow the spectrum linewidth of individual modes of an active mode-locked laser diode (ML-LD). The multiple modes of the injection-locked ML-LD lie over 3.0 THz with 25-GHz spacing at 30 dB down; their linewidth and stability, ~25 MHz, are nearly the same as those of the master laser. We also demonstrate the accurate frequency measurement of laser diodes stabilized to molecular (H(13)C (15)N ,(13)C(2)H (2)) absorption lines by use of the injection-locked ML-LD.
