Inxuntech ultra-narrow linewidth single-frequency laser module is a high-performance laser source that integrates external cavity laser (ECL) tuning and advanced packaging with precision electronic control into a single, hybrid-integrated semiconductor platform.

This module features ultra-narrow linewidth (~hundreds of Hz), high output optical power (>200 mW), superior wavelength stability, low noise, low power consumption, wide operating temperature range, compact footprint and user-friendly operation.

It is widely used in high-end industrial precision measurement, quantum communication, next-generation fiber optic sensing (DAS/DVS), high-precision ranging and velocity measurement, space coherent optical communication, fiber-optic hydroacoustic and ultrasonic monitoring, medical photonics, scientific instruments and other related fields.
