The LXM Narrow-Linewidth DFB Laser Module is based on indie’s proprietary laser diode technology. This single-frequency laser is available in both standard (LXM-S) and ultra-narrow models (LXM-U), reaching down to ﹤0.1 kHz linewidth. Ultra-low phase noise and fast frequency modulation properties make this laser unique and sets new standards in narrow linewidth lasers.
