DOGAIN
Suzhou, China
Authorized India Partner

DOGAIN Optoelectronic Technology (Suzhou) Co., Ltd. designs and manufactures semiconductor laser chips and fiber-coupled pump laser modules used to pump fiber lasers, fiber amplifiers (EDFA/YDFA) and Raman amplifiers. Their fiber coupling module range spans compact single-mode packages (3PIN, 10PIN, 14PIN) for seed and low/mid-power pumping, and high-power multimode 915/976 nm pump modules — including dual-wavelength, wavelength-locked and lightweight variants — for industrial fiber laser systems. All DOGAIN products supplied by Monotek Photonics come with full sales, integration and after-sales support across India.
