Single-Mode and Polarization-Maintaining Lasers

For many years, we have specialized in the Chinese market in the production of single-mode (including seed sources), polarization-maintaining (PM), and multi-mode lasers across the 450 nm to 1550 nm spectrum.

  • Our single-mode lasers can achieve output power ranging from 10 mW to 120 mW (with certain 980 nm and seed source versions reaching 200 mW to 800 mW).

  • The polarization extinction ratio (PER) of our PM lasers exceeds 20 dB, with optical power reaching 30 mW to 120 mW.

  • Our multi-mode lasers are available with power levels ranging from 1 W to 500 W, meeting diverse customer requirements.
