The narrow linewidth semiconductor laser series products adopt an integrated mechanical structure, combined with atomic line frequency stabilization technology, with the output wavelength precisely locked to specific atomic transition lines (852nm/780nm). Through a high-bandwidth active feedback mechanism, deep suppression of laser frequency noise is achieved, ensuring long-term continuous locking stability. The ECDL series features ultra-narrow linewidth characteristics (typical value <100kHz), power output stability <1%, and supports a mode-hop-free continuous tuning range of ≥20GHz. The laser beam quality is excellent, with fast and slow axis divergence angles less than 1mrad and 4mrad respectively, and is paired with a 30dB isolator to ensure the purity of the optical system.

This fiber-coupled narrow linewidth laser outputs 1-28mW of highly frequency-stabilized laser light via a single-mode polarization-maintaining fiber (5µm core diameter/FC-APC). It maintains an ultra-narrow linewidth of <100kHz, a mode-hop-free tuning range of >20GHz, and atomic line locking capability. A built-in 30dB isolator ensures polarization purity and system stability. It provides a plug-and-play solution specifically designed for precision applications requiring long-distance transmission, such as quantum technology and coherent sensing.
