SM Coaxial Module

Single-mode polarization-maintaining coaxial fiber-coupled laser modules integrate a semiconductor laser diode, precision fiber-coupling optics, and a compact cylindrical housing into a highly stable laser source. Compared with conventional butterfly packages, coaxial modules offer a smaller footprint while maintaining excellent optical performance. Our products are available at wavelengths ranging from 375nm to 1550nm, with output power customizable according to different wavelengths and application requirements. Optional LD driver circuits and monitor photodiode (PD) feedback can also be integrated to further improve output stability, reliability, and ease of system integration.

These laser modules feature high fiber-coupling efficiency, TEM₀₀ beam quality, high polarization extinction ratio, low power consumption, compact size, excellent stability, and high product consistency. They are widely used in laser medical equipment, biotechnology and life science instruments, laser detection, laser alignment, printing systems, and other applications requiring compact, high-performance laser sources.
