Glory Coronation | DoGain "High-quality Single-Mode Polarization Series VCSEL Chip" won the Laser Golden Shine Award New Product Award!
On March 17, 2026,"2026 Glorious Laser Award (GLA)The award ceremony was held in Shanghai. Dogain"High-quality single-mode polarization series VCSEL chips"Standing out among the products, it won the "2026 Laser Golden Shine Award" New Product Award!
Based on its independent design and process platform, the "high-quality single-mode polarization series VCSEL chip" successfully overcomes the inherent limitations of traditional VCSEL multi-mode and polarization randomness, and achieves stable single-mode and fixed-line polarization output on the same chip, while taking into account the core advantages of low power consumption and excellent wavelength stability, and achieving the performance fusion of high beam quality, high polarization stability and high output power (850nm >3mW). Meet the complex needs of the field of precision perception.
In addition, for high-precision applications, based on Dogain's self-produced single-mode polarization chip, we have independently developed a temperature-controlled TO46 module with integrated TEC cooling to ensure long-term reliable and stable operation in industrial-grade application scenarios.
