Why Techwin
Techwin is committed to providing cutting-edge technology and future development products and services for scientific research and production applications in the fields of LIDAR, fiber optic sensing, laser communication, and high power high energy laser. In single-frequency fiber lasers, short-pulse laser generation, pulse shaping and amplification have proprietary intellectual property and unique products and technologies. After years of accumulation and development, the company has formed series of products led by LIDAR laser source, fiber laser and fiber amplifier, including coherent Doppler LIDAR and time-of-flight (TOF) LIDAR laser sources
Customer Testimonials
Techwin’s single-frequency fiber lasers gave us rock-solid stability and an ultra-clean spectrum. Integration was painless, and their team helped us hit our linewidth target on the first pass.
— Elena K., Senior Scientist (Germany)
The 1.94 µm QCW source has excellent pulse-to-pulse consistency and a compact, air-cooled footprint. It dropped straight into our polymer processing rig and improved process repeatability immediately.
— David M., Process Engineer (USA)
Techwin’s C/L-band EDFA delivered the gain and noise figure we needed for our FSO/satellite link—without blowing our power budget. Stable across temperature and backed by responsive support.
— Rina S., Systems Engineer, (India)
