🗗 Beogold DAS/DVS Solutions
Beogold's 1550nm ultra-narrow linewidth laser is a proprietary low-noise fibre laser source. The uniquely designed ultra-narrow fibre filter ensures single frequency operation of the laser. Its unique temperature control and anti-vibration design eliminates impact of changing external temperature and vibration, thus achieving a stable longitudinal single mode and single frequency output. The laser offers excellent performances. It features KHz-level linewidth, low frequency noise and intensity noise, and SMSR more than 50 dB. In addition, the uniquely designed high-strength package ensures that the fibre laser module can better adapt to changing environmental conditions, such as temperature, vibration and impact, achieving longitudinal single mode, free of mode-hops. Beogold's single-frequency narrow linewidth fibre laser source delivers output power up to 50mW and higher.
