New advancements in laser technology bolster sensing capabilities with high stability and precision.
Researchers from a semiconductor company TeraXion, Canada have introduced high-power configurations for the LXM (laser xtra modulated) narrow-linewidth laser module, offering enhancements in optical performance. These developments are expected to revolutionise applications like distributed acoustic sensing (DAS), lidar systems, and other precision technologies.
The LXM series, renowned for its low-noise semiconductor design, now includes two upgraded models. The LXM-U, featuring an ultra-narrow linewidth, delivers more than 60mW of optical power. This laser’s instantaneous linewidth of 80Hz and exceptional long-term stability make it a prime candidate for DAS systems. Its improved vibration tolerance ensures reliable operation even under demanding conditions, enabling advanced local oscillator designs and multi-channel configurations.
Engineers and researchers working in fields like autonomous vehicles, industrial monitoring, and geophysics will find these upgrades particularly beneficial. The LXM-S model, designed for mid-range coherent detection, has been upgraded to offer over 70mW of optical power. With an intrinsic linewidth below 25kHz, it excels in frequency modulation responses. Such characteristics make it ideal for frequency-modulated continuous wave (FMCW) lidar and doppler lidar applications. The increased power enhances measurement range and data throughput, addressing critical demands in the sensing industry.
Both models emphasise precision and robustness, marking significant progress in laser technology. “The advancements in power and stability redefine the scope of sensing and detection technologies,” noted a researcher. These lasers demonstrate unparalleled stability and reliability, ensuring performance across diverse applications and environments.
These upgraded configurations underscore a commitment to advancing photonic solutions, contributing to a broader range of scientific and industrial applications. By offering increased optical power and superior performance metrics, these lasers open new possibilities in advanced sensing systems and data analysis technologies. The enhanced capabilities of the LXM series reflect a step forward in the development of high-performance laser modules tailored for next-generation technologies.
