Overview

Clarity NLL 1550nm Narrow Line Width Laser Module 35mW Line Width 5kHz

Clarity NLL is a compact, low-cost laser module that offers high power and extremely narrow linewidth. The laser uses ultra stable gas absorption lines in the feedback configuration to reduce the laser linewidth, indicated as<5KhZ, typically 1-2Khz. This linewidth is useful for any long baseline interferometric sensing application, such as distributed acoustic sensing (DAS), coherent LiDAR, or other applications. To support these applications, the module can also be configured to provide a linear high-speed frequency modulation capability of ± 70 MHz and a bandwidth of 1 MHz. Using standard telecommunications lasers and our own gas batteries can provide reliable and low-cost products to meet the needs of these application
